Description

HAMITA DEVICE, START/STOP COMBI BOILER, A DEVICE TO OPERATE EXISTING COMBI BOILER WITH THE START/STOP SYSTEM, AN EQUIPMENT TO OPERATE CURRENT COMBI BOILER MODELS WITH THE START/STOP SYSTEM BY BEING INSTALLED ON THE PRODUCTION LINE, A CALORIMETER DEVICE USING THESE TECHNOLOGIES AND THE ASSEMBLY TECHNIQUES APPLIED FOR THESE TECHNOLOGIES

This invention is related to an innovation on the operating system of combi boilers, which are widely used in houses, offices and all other centrally heated placed, and the new products and techniques to be used in combi boiler equipment and the installation for the implementation of the said innovation. Scope of the invention includes applications in various industries in which this technology is used and also the related products.

In the existing combi boiler technology, which has been used for more than 50 years, the combi boiler continuously measures water temperature as long as the heating function is on and operates based on starting and stopping combustion when needed. Thus, the command to start combustion is given depending on the water temperature data in the current systems. Accordingly, the water circulation pump continuously draws water from radiators to pass it through the combi boiler (it is the same for pump combi boilers with modulation feature). By measuring water temperature, the combi boiler starts combustion, or heating. In the current systems, combustion is started depending on the water temperature measurement data and it is stopped depending on the temperature of the water pumped from the combi boiler to the radiators and/or temperature of the return flow. In doing this, current combi boilers do not need any other information. Desired water temperature is set by the user on the combi boiler control panel. The radiator water temperature set by the user is the main data required for operation of the combi boiler. Current combi boilers operate the heating start and stop cycle based on the temperature values of water leaving and arriving the combi boiler. All current combi boiler heat water up to the upper temperature value defined for the water temperature measurement range preset on the mainboard. It is a must to ensure that pump operates after combustion, since otherwise the second combustion cycle cannot start. Combustion starts if the temperature of the return water carried by the pump to the combi boiler decreases to the lower temperature value defined on the mainboard. Current combi boilers operate in an infinite loop based on the operation cycle described above.

In the current combi boiler systems, since the minimum temperature value of return water in radiators is much higher than room temperature, the combi boiler starts the heating function even if it is operated in summer months (without a room thermostat) and increases aroommbient temperature. Mainboards of current combi boilers start combustion depending on water temperature, which causes additional loss of energy.

All combi boilers in the market operate in a certain temperature range dictated by the program set on the main screen, based on the information about the temperature of water leaving and arriving to radiators. As an example, although the ideal room temperature is between 24 and 26 Celsius degrees, current combi boiler switch on at higher temperatures, around 35 or 40 Celsius degrees, and heat the system water up to 40 or 50 Celsius degrees and combustion is stopped as soon as the upper water temperature limit is reached. The pump vacuums cooled water from the bottom of radiators and has it pass through the combi boiler, while water leaving the combi boiler enters in radiators at the top. For this reason, water sent to radiators cools down very soon and because of this operating principle of the pump hot water in radiators cools down rapidly while passing the whole installation, until the next combustion cycle starts. In addition, on top of the hot water sent to the radiators during combustion, cold water is added after combustion, which causes a rapid cooling down on the upper part of radiators. Because of this circulation caused by the pump, the average temperature of water in radiators is high. All these problems also cause high flue temperatures during second combustion and current combi boilers in the market have high amount of heat loss at flue and on the installation.

The start/stop combi boiler operating system described in our patent application made in Turkey with patent entry number 2015/03906 is completely different from current systems. Combi boilers described in the said patent application dated 2015 start combustion based on the climatic program loaded in the mainboard, instead of the return water temperature. The mainboard commands for heat production on the basis of calorie-based heat production and in doing this, it switches on the circulation pump only during combustion and pump is switched off simultaneously when combustion is stopped. In certain models, the pump is switched off by the mainboard after a delay in second terms. In the start/stop combi boiler system, combustion and pump operation are simultaneous, which means that combustion starts and stops together with the water pump. In this system, the mainboard starts combustion depending on the atmospheric temperature information, by taking the amount of energy to be sent to radiators as the basis. Temperature of the return water or temperature of water entering in radiators does not have any effect on the combustion command. Combustion start command is given by the climatic program set by the user. In the start/stop combi boiler, operating range for combustion time and waiting time between two combustions can be loaded in the climatic programs in the mainboard as preset time ranges, thanks to which a compressor can be used in the combi boiler. In the start/stop combi boiler design, for which an external ait (atmosphere) temperature sensor is used, combustion command is based on the atmosphere temperature value, and combustion stop command and waiting time between two combustions are also assigned based on the atmosphere temperature. During energy generation, the climatic program set on the mainboard operates the combi boiler for a while and then determines the waiting time by collecting related data and assigns the determined time when combustion is stopped. During the waiting time, the combi boiler never starts next combustion and it is only started when the waiting time is over and the pump is switched on simultaneously. In the operating principle described in our application made in 2015, we stated that water temperature is not taken as the basis for starting combustion and that combustion is started based on the climatic program loaded in the mainboard, in consideration of the combustion and waiting times. Our combi boiler with an atmosphere temperature measurement sensor is the most suitable combi boiler model for the implementation of this operating principle (since in certain new models, the mainboard with the climatic program receives atmosphere temperature data through the internet, they do not contain any physical sensor). In this combi boiler model, the mainboard starts combustion depending on the atmosphere temperature data and controls the amount of thermal energy to be generated on calorie basis. Thanks to certain features including combustion modulation, it can generate thermal energy in a range of minimum and maximum time, which is defined by the climatic program. The climatic program loaded in the mainboard determines the waiting time (the time waited before the next combustion is started) based on the atmosphere temperature value and then assigns it when combustion is stopped. Because of this operating principle, we call the combi boiler developed by us “start/stop” combi boiler. When compared to the current condensing combi boiler, our combi boiler transfers hotter water to radiators after each cycle of transfer, the pump is switched off to keep the thermal energy on the upper part of radiators. In result, temperature is kept higher in radiator upper parts, heat losses on installation pipes are reduced and flue temperature is also decreased by ensuring high condensation efficiency. In this system, temperature of return water is lower when compared to the current system, which ensures high condensation efficiency even when the combi boiler is working at high capacity. In this method, combi boiler flue temperature is reduced. The mainboard determines the time when next will start through the control panel connected to the mainboard and/or based on the climatic program set on the control screen. If the mainboard has a sensor to measure atmosphere temperature and/or room temperature, it automatically adjusts the thermal energy generation capacity and regulated all combi boiler functions depending on the climatic changes between day and night time and performs all functions automatically by operating the combi boiler on the start/stop basis. In combi boilers equipped with an atmosphere temperature sensor and/or room thermostat, the mainboard automatically determines combustion time and/or waiting time between two combustion cycles based on temperature variations to ensure high natural gas and electricity saving.

During the research studies conducted after the patent application in 2015, flame height modulation feature has been added in the software to be applied during stopping and starting of combustion. Thanks to this modification, expansion and contraction rates of combi boiler internal parts have been reduced. When combustion is to be stopped, the combi boiler gradually reduces flame height, instead of a sudden stop and stops combustion and the pump (sometimes with a delay in second terms) at the most suitable temperature value. Similarly, flame height I gradually increased when combustion is started to extend the expansion and contraction based physical life of combi boiler. The research studies also resulted in a flue system ensuring high efficiency, in which the efficiency of the start/stop combi boiler is increased to a level higher than current full condensing combi boilers. For this purpose, the“hermetic core” flue system ensuring heat transfer between cold air taken from the atmosphere and hot water discharged by the combi boiler to the atmosphere, thanks to which heat transfer is ensured between the two air masses. In this system, clean air taken to the combi boiler is warmed up in a preheating process and then it passes to the heat exchanger developed to cool down the water returning from the installation. Hot return water from radiators passes through this heat exchanger and cooled down and then directed to another heat exchanger to which toxic waste gasses from the combustion chamber are also transferred for achieving high level of condensation. Thanks to the cooled down return water, high amount of energy is absorbed from hot waste air. This way, return water absorbs heat from the flue and then sent back to radiators after being heated to the target temperature. The clean air mass subjected to preheating in the flue absorbs heat from return water to reach higher temperatures and then transferred to the combustion chamber together with natural gas. In this technique, very high condensation levels have been reached in the combi boiler developed. When the weather gets gradually colder during winter months, flue gas temperature values also decreases to ensure higher combi boiler efficiency. If the combi boiler is to be used in very cold weather, use of an anti-freezing agent may be needed for the system water. When weather temperature is about -50 or -55 Celsius degrees, temperature of clean air mass taken to the combi boiler may stay under zero despite preheating in the flue system and meet return water from radiators at around -40 Celsius degrees to overcool the return water, as a result of which return water may freeze in the heat exchanger. To eliminate this risk, freezing temperature of the system water must be reduced by adding an anti-freezing agent depending on the climatic conditions. Return water has very low risk of freezing and in order to eliminate this risk in the internal structure of the combi boiler without an anti- freezing agent, mainboard may activate the transit pass air channel to ensure that air passes directly to the combustion chamber without meeting return water for reducing the amount of cold air mass meeting return water in very low weather temperatures, based on the data collected by the mainboard. There are air flaps at the entrance of the combi boiler part containing the said air transfer channel and the heat exchanger through which return water passes. As an optional feature for combi boilers to be used in very cold climatic conditions, these flaps direct air passage to protect return water from freezing. The start/stop technique has enabled us to develop the abovementioned innovations and try new techniques to achieve high efficiency levels. In this context, the start/stop systems provided us with the opportunity to use a compressor in the combi boiler. In the current combi boiler systems, both combustion start time and combustion duration are uncertain and since it is not reasonable to use a compressor in the face of these uncertainties, the use of a compressor in a combi boiler could not be implemented successfully around the world until now. However, the start/stop operating principle developed by use offers conditions very suitable for the use of a compressor. In addition, all these technical features can be used together with the Hamita device explained in our application. As a result of the development of new operating techniques, we are planning to start serial production of the first super-condensing combi boiler. The software used for the mainboard of this combi boiler operates the equipment by monitoring four different data. In the start/ stop technology, the mainboard operates the combi boiler by monitoring atmosphere temperature. Based on this data, the mainboard automatically increases or decreases the temperature of water sent to radiators (the user may manually set the temperature of water sent to radiators to a constant value), and it also automatically determines the waiting time (the time during which both combustion and the pump are switched off) after a combustion cycle.

The combi boiler mainboard continuously measures the temperature of exhaust gas, fresh air taken in the combi boiler and return water when it leaves the heat exchanger after being cooled down by fresh air.

The mainboard software measures return water temperature to eliminate the risk of freezing and automatically controls the pump to keep exhaust temperature low. In the combi boiler model equipped with a room thermostat, the mainboard monitors room temperature to ensure better management of the pump and flame height. In this model, the mainboard controls flame height to keep exhaust temperature under a certain point. For this purpose, it measures room temperature and based on this data, it gradually adjusts pump speed while room temperature approaches to the set value. On the other hand, the mainboard also adjusts flame height to keep the temperature of water sent to radiators, as a result of which the combi boiler operates at high efficiency and low exhaust temperature.

Besides, mainboard of the start/stop condensing combi boiler measures the water sent to and returning from radiators in order to keep the amount of energy generated under control, depending on the climatic program set by the user.

While various experiments were performed for the development of the start/stop combi boiler, we have managed to develop another new combi boiler technology. This new combi boiler has a much different technology and operating system than all current combi boilers in the market. In this patent application, we will describe the improvements made on our start/stop combi boiler technology and the Hamita device containing new generation technologies. We have developed new features for the start/stop technology specified in our patent application with number 2015/03906 mentioned above. The start/stop operating principle has offered us new fields of application, thanks to which we have managed to significantly reduce exhaust temperature. Main topics we would like to have patented as a result of this application are as follows:

The techniques and components developed for reducing exhaust temperature.

The techniques and components developed for increasing combi boiler combustion chamber efficiency.

New features added to the Combi Boiler Saving Device developed for existing combi boilers.

The Start/Stop Calorimeter Device for central heating, which was developed by combining the Combi Boiler Saving Device with calorimeters.

The techniques and components developed for the installation for a more efficient start/stop system.

The additional combi boiler components developed, and the new implementation techniques in which these components are used.

Definitions of certain terms used to describe the invention are as follows:

Start/stop operating system: The general name used for the operating system in which the pump and combustion are simultaneously switched on and off during the generation of thermal energy by combustion, or in other words synchronization of combustion and pump operation.

Mainboard for the invention: Mainboard is the electronic circuit used in all combi boiler models to manage the operation of the equipment. The combi boiler adds the following invention to the electronic circuit: The mainboard operates the combi boiler with a start/stop system and it can be optionally equipped with sensors measuring atmosphere temperature and room temperature. In the mainboard is equipped with these sensors, it decides to activate the heating function of the combi boiler depending on the temperature values measured and/or the climatic program set by the user. When atmosphere temperature is lower than the certain level set in the program, the mainboard automatically activates the heating function. In the other hand, the Hamita device firstly activates the compressor and shortly after starts combustion, between which all combi boiler components are activated. While combustion is stopped when the pump is switched off in the standard design, when the Hamita device is in place, the mainboard switches off the compressor shortly before combustion is stopped and then stops combustion. Shortly after, the fan and water pump are switched off. When an atmosphere temperature sensor and/or a room thermostat are installed on the mainboard developed by us, the background software becomes activated based on the program set by the user and operates the combi boiler in the start/stop system. It determines the combustion time and then waiting time during which the water pump is switched off. These functions are performed by the mainboard in an infinite loop. In the climatic programs, pump waiting time, amount of the energy to be generated and combustion time are embedded and when the user makes a setting by use of the control button, new data are activate. When an atmosphere temperature sensor and/or a room thermostat are installed on the mainboard, the new program compatible with the sensors are automatically activated and the former program is deactivated. All these programs operate the combi boiler and all related units in the start/stop system.

Start/stop button: When this button is pressed, the combi boiler activates the winter mode and continuously operates during the time defined in the mainboard. Although this feature was developed for the combi boiler saving device for hot water utilisation, it will be used in all newly produced combi boilers. In order to allow fast heating of the house or the space, this function will be present in mainboards of new combi boilers.

Tl, T2, ... buttons: The function of these buttons is to accommodate the climatic programs. By use of these buttons, the user selects the operating program of the combi boiler, which in turn adjusts the combustion time and water pump waiting time of the equipment. When the Tl, T2, ... programs loaded in the combi boiler mainboard are fed with the atmosphere temperature sensor and/or room thermostat data, a more comfortable and economical use is offered the user. Hamita: It is the new generation heating and cooling device developed by combining the start/stop condensing combi boiler, air conditioner and heat pump technologies and the addition of new implementations. The name of the device was given based on its new technical and technological features.

All current combi boilers in the market are equipped with a mainboard (an electronic card) to direct the combi boiler functions. However, there is no other mainboard (an electronic card) equipped with the functional features of our product. While the invention will be used in newly produced combi boiler as a mainboard, existing combi boiler can be also equipped with this technology by integrating the mainboard to the electric network feeding the combi boiler as an external independent unit (Combi Boiler Saving Device), or adjacent to the mainboards of current combi boiler as device. The innovation made on the operating system of the combi boiler mainboard software is also offered to combi boiler producers as additional equipment shown in the drawings. We are also targeting to produce a combi boiler saving device for different models of existing combi boilers. For newly produced combi boiler, this mainboard (electronic card) can be placed in the casing by way of integration.

In the system subject to our application, by adding the room temperature sensor to the start/stop (including the water circulation pump) principle described in our initial application, the mainboard has been converted into a more successful climatic operation algorithm. In this context, new innovations made after the initial application are as follows: Starting of combustion with low flame height and gradual increasing of it with the flame height modulation feature, and gradual reduction of flame height to stop combustion simultaneous with or shortly after the pump. Addition of a new feature in order to preheat fresh air before being fed into the combi boiler and precool return water.

Operation of the combi boiler by the start/stop in line with the start/stop principle, thanks to the data fed by the room temperature sensor (room thermostat).

Achieving lower exhaust temperatures based on the data collected, and to increase or decrease the pump speed and/or flame height in order to achieve this.

Operation of the combi boiler in the start/stop system depending on the atmosphere temperature and room temperature variations through the automatic activation of the software loaded in the mainboard by integrating a room thermostat to the mainboard.

Operation of the combi boiler in the start/stop system depending on the atmosphere temperature variations through the automatic activation of the software loaded in the mainboard by integrating an atmosphere temperature sensor to the mainboard.

Addition of a compressor to the combi boiler in order to reduce exhaust temperature and addition of new units to allow heat transfer by the compressor.

In order to reduce exhaust temperature, the software loaded in the mainboard switches on the compressor shortly before starting combustion, and switches off it shortly before stopping combustion.

When hot water is demanded, combustion and compressor may remain switched off. The air channel system is bypassed to ensure that the return water and fresh air meeting function is deactivated when hot water is demanded from the combi boiler. This channel system is occasionally activated during the heating of radiators in order to deactivate the cooling down of return water and eliminate the risk of freezing in heat exchangers.

The operational software automatically increasing or decreasing the temperature of water sent to radiators has been added in the main software in order to keep return water temperature low, which in turn provides high efficiency gain.

Since current combi boilers in the market keep circulation water pumps in constant operation and the pump must provide the water temperature data to the mainboard, even if it occasionally stops, significant heat losses occur on the installation between the combi boiler and radiators. Since, these installations are generally placed in the outer shell of buildings, the thermal energy generated by the combi boiler is absorbed by the concrete block and transferred to the atmosphere through the building shell. The mainboard (electronic card) subject to our application ensures that the combi boiler operates in the start/ stop principle, which switches off the pump when necessary and ensures significant reduction of heat losses on the installation. Thanks to this operating principle, return water temperature is decreased, which enables cooling down of exhaust by use of return water, or complete cooling down of return water by use of a low capacity compressor. By passing return water through the exhaust before the combustion chamber, high amount of energy is absorbed and exhaust temperature is significantly reduced. The start/stop system has enabled the development of all these innovations. The integration of an atmosphere temperature sensor and/or a room thermostat to the mainboard has enabled much more efficient operation.

Under the invention, the mainboard (electronic card) developed controls all functions of current combi boilers and in addition, it monitors atmosphere temperature to calculate the amount of thermal energy required to be generated. If a room thermostat is also used, the mainboard also monitors room temperature based on the data sent by the sensor and switches on the compressor shortly before starting combustion and switching on the pump to work a certain period (the combi boiler operates as long as combustion is active and in certain models, the water pump can be activated a few seconds in advance). Afterwards, the mainboard switches off the compressor shortly

Before stopping combustion and then combustion is stopped and the pump is switched off with a delay of seconds. Until the next thermal energy production cycle (until the next combustion), the water circulation pump and other components are switched off by the mainboard and in this system, the combustion start command is given in a very different technique when compared to the current combi boiler operating systems.

When the combi boiler saving device is used, electric current is fed to the combi boiler for a certain period depending on the atmosphere temperature. During this period, if the winter setting was selected, the combi boiler activates the combustion system to produce thermal energy and when the thermal energy amount needed by the user is generated, combustion is stopped and electric current to the combi boiler is completely cut, as a result of which the combi boiler saving device switches off all combi boiler functions including the water pump. The mainboard (electronic card) program determines operation and waiting times depending on the atmosphere temperature (including the circulation water pump) and this procedure is repeated in an infinite loop. While all these features were presented in the application made in 2015, the following features are added to the combi boiler saving device with this application:

The following features have been developed in order to eliminate the problem of delayed hot water transfer to tap for bathroom or kitchen use, when the combi boiler is powered by our saving devices in certain models: a) In order to ensure that the combi boiler saving device to control the combi boiler in the start/stop system through the thermostat connection line on the existing mainboard of the equipment, instead of controlling it through the mains power line, a room temperature measurement sensor has been integrated to our mainboard. Thanks to this, the device measures both atmosphere and room temperature and operates the combi boiler in the start/stop system. In addition, the combi boiler saving device can be installed on the room thermostat inlet, in addition to the combi boiler power line. The combi boiler can be connected to the saving device both on the power line and the on/off room thermostat line. Shortly before the electric power to the combi boiler is cut, the device stops combustion with a command given through the room thermostat socket and only after this power is cut. When it receives related command via the water socket, the device feeds power to the combi boiler, but if radiator heating was not demanded by the user, it keeps the combi boiler in the summer operation mode via the room thermostat socket.

b) If the Combi Boiler is used in a system with a water sensor, when the tap is opened and then closed, our combi boiler saving device continues to feed power to the combi boiler for a while. In result, while hot water is used in the bathroom is kitchen, there is no delay in the transfer of hot water to the tap when the tap is opened and closed in short intervals, which ensures water savings during winter months. This software feature has been added in the combi boiler saving device. When hot water is demanded by the user, although power is fed to the combi boiler, the room thermostat is in off position and the combi boiler does not activate the winter operating mode, if room temperature is in the demanded range.

c) Some of our models allow the integration of certain software features to enable remote control by use of mobile applications. When our GPS integrated mobile application is used, the application actives the combi boiler in the start/stop system and tries to reach the targeted room temperature, depending on the distance of the user to the combi boiler. d) In order to operate the combi boiler in the start/ stop system through the room thermostat developed by us, the software feature switching off the pump after the combustion is stopped should be integrated to the mainboard. In result, the pump is switched off after at the end of every combustion cycle.

This mainboard (electronic card) software, developed for existing combi boilers, is integrated to the mains power feeding the combi boiler in a device (combi boiler saving device) and operates the combi boiler in the start/stop system to reduce exhaust temperature with high condensation efficiency.

Based on the invention and related innovations made on the operating system, we are planning to produce and market several digital and analogue combi boiler saving device models (room thermostat feature and remote control over the internet with mobile applications). The invention makes it possible to integrate the new mainboard (electronic card) to the newly produced combi boilers to measure atmosphere temperature with an independent sensor, and also make measurements on the fresh air taken by hermetic and condensing combi boilers in the flue to define the program to be used. As the intellectual part of the invention, atmosphere temperature and/or room temperature is measure and the software operates the combi boiler in the start/stop system to generate the exact amount of thermal energy needed. Thus, the combi boiler water circulation pump is switched off until energy generation is needed and significant energy saving is provided in the start/stop operating system. The mainboard, which operates with an atmosphere temperature measurement sensor and/or a room thermostat, relies on the innovation made on the combi boiler mainboard software operating system. The software installed in the combi boiler saving device works as a timer for determining operating and waiting times and controlling the combi boiler in this loop.

The advanced mainboard software used in the new combi boiler saving devices and our solutions including the mainboard software to the offered to combi boiler producers calculate the amount of energy needed by the user and operate the combi boiler for a short duration (water pump is switched on only during combustion), and then switches off the water pump until energy generation is needed again. The software relies on the abovementioned innovations. The water flow sensor in combi boiler saving devices will be offered to users as an optional feature, while the use of a water flow sensor is a must for the use of the new mainboard in the combi boiler design. The combi boiler saving device can be connected to the combi boiler both on the power line and/or the combi boiler room thermostat socket. When the room heating function is to be stopped, firstly combustion is stopped via the room thermostat socket and then cuts power supply to the combi boiler to switch off the pump. As an installation option, users may decide to connect the combi boiler to our device on the power line or not.

The mainboard (electronic card) to be installed in existing mainboard, equipped with our start/stop technology, minimises energy losses in combi boilers, increases energy efficiency and also reduced exhaust thermal loss. This operating system, developed for climatic change stages, provides significant level of energy saving and, in particular, reduces exhaust temperature. In spring and fall months, during which the atmosphere temperature is not very low, the amount of energy required to be generated by the combi boiler and temperature of return water are very low and the compressor operates easier. In result, thermal energy in the combustion chamber is absorbed much better by return water and exhaust temperature is reduced even more by use of the compressor. This technique ensures higher combi boiler efficiency.

The operating principle of current combi boilers in the market relies on the continuous work of water circulation pump, since combustion is started based on the temperature of the water passing through the pump. For more than 50 years, current combi boilers give combustion start command based on the temperature of return water and they cannot switch off the circulation pump after combustion, depending on atmosphere temperature. While some models of current combi boilers have a special program to prevent water freezing and resulting damage, this does not provide energy saving. The thermostat measuring atmosphere temperature is this type of combi boilers is to activate the combi boiler when necessary to prevent water from freezing, when the combi boiler is out of operation for a long period of time which has nothing to do with the software features of our invention. In addition, certain current combi boiler models have software to switch off the circulation pump for preventing it from burning as a result of excessive temperatures. Again, this type of software do not intent to provide energy saving and they are not related to our software innovation. Besides, certain combi boiler models have the feature to switch off the pump after the combustion cycle, but only defined for a fixed period of time. After the certain duration defined, the pump is switched off. Since this type of combi boilers also start combustion depending on water temperature, it is not certain that combustion will occur when the pump is switched on. On the other hand, in our system, combustion is started and stopped in synchronization with the pump and combustion start command does not rely on return water temperature. In addition, since current combi boiler models have to measure return water temperature, cool water vacuumed by the pump from the lower part of radiators when there is no combustion loses heat while passing the installation, and sent back to radiators in low temperatures. This manner of operation is quite negative from the point of efficiency, since upper parts of radiators quickly cool down and radiators’ heating capacity decreases. Besides, since hot and cold water are always mixed in the current technology, average water mass in the system remains at high temperatures and losses on the installation increase. In addition, water temperature increases together with room temperature, and return water reaches the combi boiler at higher temperature, exhaust temperature increases and combi boiler operating efficiency decreases in turn. The start/stop system developed by us has eliminated all these problems and increased the operating efficiency of combi boilers. Thanks to the cooling of return water by use of the fresh air taken in the combi boiler, combi boiler efficiency does not decrease in colder weather and on the contrary, it increases. The mainboard developed performs all functions of electronic cards used in current combi boilers and in addition, it monitors atmosphere temperature and room temperature to calculate the amount of energy required to be generated by the combi boiler. The most importance distinctions here are as follows: Combustion and pump operation start and stop in a synchronized manner. The waiting time after combustion is automatically and variably assigned by the climatic program, based on the measurement data sent by the atmosphere temperature sensor and/or room temperature sensor.

In the start/stop system, starting of combustion and thus heating do not depend on water temperature.

The main objective of the start/stop system is to keep the temperature of water sent to radiators high, while temperature of water returning to the combi boiler is as low as possible, and to decrease exhaust temperature as much as possible for higher efficiency.

While the energy generated is sent to radiators by the water pump, mainboard of the start/stop system calculates the waiting time and switches of the circulation pump to ensure energy saving in terms of electricity consumption.

The mainboard measures the amount and temperature of water sent to radiators and also temperature of return water to control the amount of energy generation accordingly. The user may change the energy program on the control panel. The program set functions depending on the atmosphere temperature and/or room temperature. Based on the atmosphere temperature, the active program automatically control the amount of energy to be generated and then the waiting time, and it also calculates combustion time by measuring temperature temperature.

In our combi boiler model without any temperature sensor, the user increases or decreases the working and waiting times by turning the capacity button. In this combi boiler type, the mainboard controls the amount of energy to be generated together with a timer program. Waiting time is defined by the user through program selection and combustion starts at the end of every waiting period. Depending on the temperature of return water, temperature of water sent to radiators is automatically adjusted by the combi boiler mainboard and the user may set this value to a constant value. Some climatic programs keep the amount of energy to be generated constant and the combi boiler is controlled by the mainboard in terms of the waiting time after combustion.

The mainboard (accommodates the software) and/or the mainboard (electronic card) connected to it contains logic for the operation of the combi boiler for a period and switching off the circulation pump and other components afterwards.

The mainboard (electronic card) and/or the innovation made on the combi boiler mainboard operating system (accommodates the software) includes the software that determined the combustion and waiting (switching off combi boiler heating, including the pump) times, depending on the amount of energy to be generated in line with atmosphere temperature.

When the mainboard (electronic card) is integrated to the mainboard our solutions accommodating the related software are installed on the mainboard, the following operating logic is implemented: Shortly after the required amount of energy is generated and combustion is stopped, the circulation pump is switched off, which extends the economic life of the equipment by minimising the formation of lime layers and corrosion on the internal surface of the burner in the combustion chamber. Thanks to the modulation feature of the mainboard, flame height is gradually increased or decreased during the starting and stopping of combustion respectively.

In the innovation made on the combi boiler mainboard software operation, since certain models do not have an atmosphere temperature sensor, the user rotates the button of the device or presses the Tl, T2, ... buttons to operate the combi boiler with the correct software (the software defining combustion and waiting times) in the mainboard (electronic card). This feature can be added to the newly produced combi boilers. In this type of combi boiler, combustion and waiting times are set by the user as constant values on the control panel. After every waiting period, the pump is switched on together with combustion and the mainboard adjusts water temperature by measuring the return water temperature.

When the mainboard (electronic card) is installed in the combi boiler, there will be no problem, since it will work in direct connection with the water flow sensor, temperature sensor measuring the temperature of radiator water, three-way valve, exhaust sensor and other combi boiler components. When the mainboard (electronic card) is installed, it will additionally measure atmosphere temperature and room temperature and switch off the circulation pump depending on the actual need of energy generation to provide energy (natural gas and electricity) saving. However, as another the innovation made on the combi boiler mainboard software operating system, the combi boiler saving device, which can be installed on the mains power line independent from the combi boiler or on the atmosphere connection or through a special socket for existing combi boilers, completely cuts electricity feeding to the combi boiler to operate the equipment compatible with the program, or it can be installed through the room thermostat socket for certain combi boiler models to operate the equipment in the start/stop system. As an alternative, it can be connected on both the power line and room thermostat socket. In addition, when a button on the device is pressed, it feeds continuous electricity to the combi boiler for a period, but checks the combustion conditions by use of temperature sensors through the room thermostat. When the conditions are not suitable, it keeps the combi boiler in the summer operation mode through the room thermostat socket to prevent hot water transfer to radiators. This feature is added on the combi boiler saving device as an option to enable users to use hot tap water during the year. Besides, the device has an on/off button that can be used to completely deactivate it to feed continuous electricity to the combi boiler. In addition, a water flow sensor is installed to the mains water inlet. The data sent by the water flow sensor are read by the combi boiler saving device continues to feed electricity to the combi boiler until a second command is given, which means the tap is closed. Some models continue to feed electricity to the combi boiler for a while after the tap is closed. For existing combi boilers that are not suitable for the use of a water flow sensor, the device will have a button to function as a time-delay relay. Our products containing the mainboard, as shown in the drawings, can be also installed on newly produced combi boilers and ensure energy saving by defining combustion and waiting times depending on the data sent by the atmosphere temperature sensor of the combi boiler. The mainboard software specified in our application can be offered as mainboard software for newly produced combi boilers and also it can be offered to combi boiler producers as implementation models containing the operating logic of our invention. The product will be connected to the combi boiler mainboard on the production line to operate the combi boiler in the start/stop system. Certain models will show the climatic program set by the year and other related information on the display.

Another product will be offered for being installed on existing combi boilers to operate them in the start/stop system, as a combi boiler saving device. In needed, different modules with different software can be produced for varying climatic conditions of different countries. In addition, products for operating combi boilers from a distance through the room thermostat socket and/or via a different connection method will be developed together with related combi boiler control software and hardware.

Thanks to the abovementioned software implementation, we have made improvements on certain combi boiler components and developed new combi boiler components to increase efficiency. These components can be installed separately or in combination, depending on the capacities of combi boiler to be produced.

- Our alternative implementations developed for reducing exhaust temperature: A) Bithermic heat exchanger for higher condensation efficiency. We have developed two different bithermic heat exchangers for this purpose. 1- This heat exchanger model is installed in the combi boiler in the same direction with gravity force. Heating unit of this bithermic heat exchanger is located on the top part. Hot water moves upwards in the spring shaped pipes surrounding the combustion chamber that contains the hot air mass generated by the he heater and absorbs thermal energy. Before reaching the combustion area, this water mass passes in the spiral shaped structure under the lower part of the combustion chamber and rises in the pipe by gaining heat. The hot water heating the return water gets cooler move downwards in the spiral shaped line and the heated hot water passes in the spiral shaped structure to reach the combustion chamber. The spiral shaped structure ends at the entrance of the combustion chamber and the rising hot water absorbs thermal energy around the burner and moves to radiators by leaving the combustion chamber from the top. The hot air mass in the combustion chamber enters at the top of the spring shaped structure to heat the return water and it cools down while moving downwards. Thus, the hot ait coming from the burner moves downwards in a spiral route and loses heat. Inside this air line, there is the water line to carry the water moving upwards by gaining heat. In this method, which makes use of gravity force and advantages of density, air mass is cooled down and sent downwards. Drawing of this heat exchanger design is submitted in our application as a sample.

2- This heat exchanger model is installed in the combi boiler in the same direction with gravity force. Under the combustion chamber that contains the hot air mass generated by the he heater, thin bithermic heat exchangers are placed downwards in layers, on top of each other. Heat exchangers are surrounded by the insulated combustion chamber. Heat exchangers were designed for being assembled to each other easily. In this implementation, hot ait in the combustion chamber gradually cools down and sinks downwards, while the water mass gradually gains heat and raises as a result of the decrease in density. Hot water, which is heated by use of plate type heat exchangers, arrives to the burner division are moves around the burner to raise, and leaves the combustion chamber at the top to be sent to radiators. In this method, which makes use of gravity force and advantages of density, air mass is cooled down and sent downwards. Drawing of this heat exchanger design is submitted in our application as a sample.

B) New hermetic core combi boiler flue.

This flue design ensures fast heart transfer through the incoming and outgoing air mass, drawings of which can be found attached.

The flow line of the hot air mass entering in this flue is covered with a felt with high heat insulation properties and by being directed by the felt structure, hot air moves to the thin channels around the pipe. After contact with hot air, outer surface of these thin channels transfer the thermal energy absorbed from hot air to the fresh air taken. Thanks to this thin heat exchanger plates contacting both the fresh air taken and hot air discharged by the combi boiler, thermal energy is transferred from discharged air to fresh air. The flue structure developed by us increases the heat transfer surface thanks to thin heat exchanger plates. Air moving through these thin plates rapidly loses heat towards the outlet, while the fresh air taken into the flue gradually gains heat when moving towards the combi boiler. Hot water is linearly blown outside through the heat exchanger plates. There are suction channels to take fresh air at the end of the flue. This flue design ensures heat transfer between incoming and discharged air masses. It can be separately sold for being installed on existing combi boilers. It design can be circular or in other geometrical shapes. We have also developed a combi boiler flue design with high heat transfer bars. In this flue, the inner spiral pipe through which hot water is discharged to the atmosphere has holes for placing the bars and the bars are placed in these holes by use of seals. This way, the bars absorb the thermal energy contained in the discharge air on one end and transfer it to the fresh air mass on the other end. The discharge air is cooled down, while fresh air is heated.

C) Thermal bridge for the reduction of exhaust temperature. This implementation has two different types. a- Cooling down of the hot return water by use of the fresh air taken into the combi boiler.

In order to cool down the return water, cold fresh air taken from the atmosphere moves to a heat exchanger. In this heat exchanger, hot return water passes through the honeycomb and loses heat. Afterwards, in order to reach high condensation levels, cooled down return water is transferred to the heat exchanger located in the division through which the toxic gasses from the combustion chamber passes. Thanks to the cooled down return water, high amount of thermal energy is absorbed from the discharge air. Return water is then heated in the combustion chamber and sent back to radiators. The fresh air preheated in the flue gains heat while it cools down return water and then it is sent to the combustion chamber together with natural gas. This technique offers very high condensation efficiency. When weather temperature gradually decreases in winter months, exhaust temperature of the combi boiler also decreases and the combi boiler reaches high efficiency levels. If this combi boiler is to be used in very cold weather, it is required to add anti- freezing agent in water to prevent freezing. Otherwise, the fresh hair taken into the combi boiler may remain under zero Celsius degrees despite preheating in the flue. In atmosphere temperature around -35 or -40 Celsius degrees, preheated fresh air meets with return water at around -20 Celsius degrees and it may freeze return water in the heat exchanger. In order to eliminate this risk, freezing temperature of water must be decreased by adding a freezing agent. b- Cooling down of return water by use of a compressor.

1- In order for the better absorption of the thermal energy in the discharge air, return water is cooled down and it absorbs the thermal energy of discharged air in the flue. In certain models, the thermal energy absorbed from return water by use of a compressor is firstly transferred to the utility water kept in a tank. When the utility water in the tank is heated, thermal energy is again transferred back to the return water. In this system, the warm return water mass is firstly cooled down, which afterwards efficiently absorbs the thermal energy in the discharge air before it is discharged to the atmosphere, as a method of heat recovery. This thermal energy, absorbed from the discharge air and transferred to return water, reduced exhaust temperature and provides energy saving. Details and operating principles of this technique are as follows:

- The system has compressor evaporators and condensers to absorb the thermal energy in the exhaust air discharged by the combi boiler.

- The compressor firstly absorbs the thermal energy in return water by use of a compressor to cool it down, and then this water mass is passed through the combi boiler flue to recover thermal energy. Afterwards, the low pressure air mass, which absorbs the thermal energy in the return water, is sent to the condenser made of thin pipes that are thicker than capillary tubes. This condenser is located in a tank full of utility water. The gas, which hardly moves in the thin pipe, becomes denser, since it is also compressed by the compressor, and leaves thermal energy to the surrounding water to heat it. When the utility water in the tanks is heated, condensation stops and the gas leave the thin pipe. After absorbing the thermal energy in the flue, it passes to the main condenser placed in the heated water mass. Since there is a drier and capillary tubes at the outlet of this condenser, the gas gets compressed in it and transfers its energy to the return water which was cooled down on the way from radiators and then heated in the flue. In this way, exhaust temperature is fairly reduced to increase efficiency. At the end of the process, return water is heated by combustion.

- Return water passes to the combustion chamber, after it is heated by the transfer of thermal power absorbed in the flue. After being heated through combustion of natural gas, it is sent to radiators.

- This system makes use of the advantages offered by the start/stop system. In this system, the compressor is switched on shortly before the circulation pump to increase evaporator efficiency. Afterwards, the combi boiler starts combustion together with the propeller and circulation pump. - When combustion starts, the whole system works and exhaust temperature is very significantly reduced.

- Thanks to the preheating of utility water, the combi boiler always contains some amount of hot water. This way, waste of water resulting from delayed combustion in hot water use from the tap is reduced. Current combi boilers wait for a while before starting combustion when the tap is opened, which causes waste of water. This technique partly eliminates this problem.

- The three-way valve is activated during hot water use from the tap and the whole thermal energy absorbed from the flue is transferred to the utility water. In our certain domestic type combi boiler models, the compressor is not activated during hot water use from the tap.

- The compressor is switched off shortly before combustion is stopped. Afterwards, combustion and the propeller are stopped together, shortly before the circulation pump is switched off. This way, the combi boiler is operated in the start/stop system.

C- By use of the compressor, thermal energy contained in the discharge air is absorbed and transferred to the utility water tank, and then to the fresh air taken from the atmosphere. Thermal energy discharged by the combi boiler is absorbed by use of the compressor and evaporator. Recovered thermal energy is firstly used to heat the utility water and as the utility water gets hotter, thermal energy is transferred to the cold fresh air mass by use of the condenser. The method explained here is operated in an infinite loop and exhaust temperature is reduced to increase energy efficiency of the combi boiler.

2- Thermal energy contained in the discharge air is absorbed and transferred to the utility water and then to the cool return water to ensure energy saving. By reversing this process, the natural gas combi boiler can be converted to a cooling device. Details and operating principles of this process are as follows: - By use of a compressor and an evaporator, thermal energy contained in the discharge air is absorbed.

- The low pressure air mass containing the thermal energy absorbed from discharge air by use of the compressor is sent to the condenser made of thin pipes that are thicker than capillary tubes. This condenser is located in a tank full of utility water. The gas, which hardly moves in the thin pipe, becomes denser, since it is also compressed by the compressor, and leaves thermal energy to the surrounding water to heat it. When the utility water in the tanks is heated, condensation stops and the gas leave the thin pipe to pass to the main condenser that is placed in the return water between 20 and 40 Celsius degrees. Since there is a drier and capillary tubes at the outlet of this condenser, the gas gets compressed in it and transfers its energy to the return water to heat return water.

- Return water is heated by the transfer of the thermal energy absorbed from the exhaust, and it is sent to the combustion chamber. After being heated by natural gas, it is sent to radiators.

- This system makes use of the advantages offered by the start/stop system. In this system, the compressor is switched on shortly before the circulation pump to ensure that the evaporator is cold enough to absorb the thermal energy from the discharge air. Afterwards, the combi boiler starts combustion together with the propeller and circulation pump.

- When combustion starts, the whole system works and exhaust temperature is reduced to around zero Celsius degree and even to minus temperatures in certain models, as a result of which significant energy efficiency is obtained.

- Thanks to the preheating of utility water, the combi boiler always contains some amount of hot water. This way, waste of water resulting from delayed combustion in hot water use from the tap is reduced. Current combi boilers wait for a while before starting combustion when the tap is opened, which causes waste of water. This technique eliminates this problem.

- -The three-way valve is activated during hot water use from the tap and the whole thermal energy absorbed from the flue is transferred to the utility water without switching off the compressor. When hot water is demanded while the radiator heating function is deactivated, the compressor is not activated.

- The compressor system was developed for space heating. The compressor is switched off shortly before combustion is stopped. Afterwards, combustion and the propeller are stopped together, shortly before the circulation pump is switched off. This way, the combi boiler is operated in the start/stop system.

- By reversing this process explained above, our combi boiler can has been added the feature to cool the space. In summer months, thermal energy of warm return water is absorbed and water is sent back to radiators after its temperature is reduced to 20 Celsius degrees. With this process, the combi boiler operates as a cooler in summer months. In this process, based on the data sent by combi boiler sensors, the propeller, circulation pump and the compressor added to the combi boiler always switch on and off together by functioning as a start/stop unit. If demanded by the customer, an external unit can be installed to the combi boiler to increase the cooling capacity. The external unit added, which is similar to external units of air conditioners, allows faster discharge of the thermal energy absorbed from water to the atmosphere. External units consist of a condenser and a propeller.

This heat transfer technique used in natural gas combi boiler is different from current practices. In our technique, thermal energy of the toxic gas mass, which has been heated by use of natural gas and intended to be discharged to the atmosphere, is absorbed. The heat transfer technique deployed depends on gradual pressure formation, which ensures heat transfer. With the effect of the pressure formed in the first tank by use of thin pipes, gas is liquefied and it transfers the heat it has absorbed from the flue to the utility water. Then, as the temperature of the utility water tank increases, gas condensation rate decreases and it completely stops after a certain point. Uncondensed gas flows into a condenser placed in the second tank. Thanks to the pressure effect created by the copper capillary pipe and drier placed to the other end of this condenser, high pressure is formed in here. The gas gets condensed under this high pressure and transfers thermal energy to warm return water mass. In this technique, heat transfer is made to liquid in two separate tanks to ensure system efficiency. In our design, thermal energy is firstly transferred to the utility water and secondly to the water mass that was previously heated by use of natural gas. This technique is not directly equivalent of the operating principles of an air conditioner or heat pump. We provide energy efficiency by absorbing thermal energy of toxic discharge gas at high temperatures. When this technical feature and the combi boiler operation in which combustion is not made based on the return water temperature considered together with all innovations developed by us for combi boilers, it can be seen that a new efficient combi boiler technology has been created for the use of humanity. The product developed by us in fact not a combi boiler, air conditioner or heat pump. A new operating principle has been developed by adding new techniques through the combination of common arguments of these three technologies. This is a new commercial product operating under the start/stop principle, with a very different main principle. We call this new commercial product technology as“Start/Stop Hamita Combi Boiler”. Thanks to this technique, the circulation water pump used in the combi boiler allows economical use with low energy consumption. Since the mainboard of start/stop combi boiler switches off the pump when there is no need for heating, the energy saved is used for the operation of the compressor in models equipped with a compressor, and total energy consumption is at the same level with current condensing combi boilers, despite the use of a compressor. Thanks to this technique, daily energy consumption of a start/stop combi boiler is very near to a conventional condensing combi boiler with similar heating capacity. In result, the amount of electricity consumed by the combi boiler developed by us is near to condensing combi boilers with similar heating capacity. On the other hand, when compared to conventional condensing combi boilers, exhaust temperature is reduced by up to 50 Celsius degrees. In our technique, combi boiler efficiency is very significantly improved. In heat pumps, mains water is heated by use of electric power, when atmosphere temperature is very low. Many disadvantages including this one is eliminated by this technology and a product with high efficiency is offered to consumers for domestic use.

The method described above works in an infinite loop. Exhaust temperature is reduced, energy efficiency is increased and most importantly, contribution is made to the reduction of the effects of climate change caused by global warming. In this system, the combi boiler sends water to radiators at higher temperatures and the equipment used for heating can be also used for cooling, which provides a new advantageous product for consumers.

In addition to the abovementioned technique, the technique and operating principle intended to be used in the combi boilers with the start/stop technology are as follows:

Thermal energy of the hot air mass discharged to the atmosphere is absorbed by use of a compressor. Absorbed energy is firstly transferred to utility water and secondly to the return water which has been cooled down by fresh air taken from the atmosphere. In result,

The air is discharged to the temperature is low temperatures, after its energy is absorbed,

Since return water is cooled down by fresh air taken in the combi boiler, compressor efficiency and condensation efficiency in the combustion chamber significantly increase,

Risk of freezing in the evaporator connected to the compressor is very low, since return water is cooled down in the flue, In the combi boiler equipped with this technology, the compressor switched on shortly before the end of the waiting time, before combustion starts and it is switched off shortly before combustion is stopped, which eliminates prevents on the evaporator. D) One of the most important problems of combi boiler is resetting and the resulting deactivation of the heating function, caused by loss of water in the system. With a software feature developed by us, water replenishment in the combi boiler is automatically performed. The amount of water added does not exceed a certain amount in litres. The amount of water to be added is calculated by the mainboard, in consideration of the last water replenishment date and replenishment is performed automatically. When the amount of water added reaches the amount defined in the software, the combi boiler gives audio warning to the user and in certain models, it sends information to the mobile software. When the amount of water added is excessive, the mainboard closes all solenoid valves located at all system inlets and outlets and takes the combi boiler to the safety mode. If there is risk of freezing, it switches on the combi boiler for a short time. This way, the risk of flooding is minimised.

E) We have tried some techniques on the water installation during the development of the start/stop system in order to improve the performance of compressor and heating even more. In result, we have developed the optimum water installation model, as a result of which the combi boiler started to operate in higher efficiency.

Properties of this method, called the Alimo technique, are listed as follow:

The hot water installation transferring water from the combi boiler to radiators should be covered with insulating materials and pipes with good insulation properties should be used.

Radiator sizes should be increased by at least 20% when compared to the radiators used for conventional condensing combi boilers. Return water line should be passed through hallways in order to transfer any lost thermal energy to the concrete floor.

The use of secondary radiators called Fanpet, to which return water pipes are connected, provides significant level of efficiency gain.

Return water lines should be installed in the longest route possible in order to allow as much as possible loss of heat to the space, and pipes with high thermal conductivity should be used.

Return water line should pass through the floor of the common use areas of the house or other space heated and the Alimo floor collector should be used. Alimo heat transfer technique: This is the general name given for the products and techniques developed for sending water to radiators with minimum loss of heat and ensure fast loss of heat in return water. General principles of this technique are described above. Two different products have been developed by us, in addition to the abovementioned techniques.

a) In newly constructed houses, hot water lines reaching radiators are insulated against heat loss. In order the ensure that return water transfers its whole thermal energy to the floors of common use areas, return water line is passed through the longest route. A special apparatus developed by us is used in order to ensure that thermal energy is completely transferred to the floor concrete along hallways and in the kitchen. If possible, return water pipes are brought together in a collector before the said apparatus and the return water pipes are connected to the Alimo floor collector in s single line. If it is not possible to bring all lines together, one Alimo floor collector is connected to each return water line. The line from the collector is laid up to the combi boiler in the hallway and kitchen floor. This apparatus has left and right legs and it is made of stainless steel. The special technique used in the design of legs ensures high level of heat transfer. Additionally, pipes with high heat transfer properties are used for the return water line in newly constructed houses. Thanks to these techniques, return water temperature is reduced under 20 Celsius degrees. b) Alimo Fanpet is used in previously constructed houses and workplaces. Alimo fanpet is a new generation radiator being developed by our team. On the inlet of this radiator, there is a sensor detecting water flow, which sends information to the electronic circuit reading the flow data. There are fans connected to the circuit and fans are operated only when there is water flow. Alimo fanpet is installed on the return water line all return water is passed through one or more fanpets. Fanpet sends command to the electronic card via sensors detecting water flow. As long as there is water flow, electric fans are automatically operated for fast heat transfer from return water. These fanpet radiators can be used as radiators in many spaces of newly constructed houses. In particular, in rooms or spaces having“Italian style” windows, radiators are not placed under windows. Instead, they are placed in other points of the room. In winter months, hot and cold air meeting on the glass causes condensation on the glass as a result of hot and cold air meeting on the glass. Drops caused by condensation cause damage on the wall behind the radiator and wooden floor under the radiator. Thin Alimo Fanpets are placed as second radiators under windows to eliminate condensation and water drops on the glass. Return water coming from the primary radiator of the room is passed through fanpet and it cools down there. Return water leaving fanpet is completely cooled down by use of the Alimo installation technique and it reaches the combi boiler after losing a high amount of thermal energy. Thanks to fanpets, the cold air mass flowing through walls and windows to room floor is prevented and the temperature difference between room ceiling and floor is reduced to ensure a healthy environment. The fanpet technology can be offered as portable equipment for being installed under radiators. This way, users may have both a combi boiler heating system and a cooling system for summer months without replacing radiators.

Our start/stop combi boiler making use of the abovementioned techniques generate the same level of thermal energy with current condensing combi boilers, by consuming less natural gas. We aim to increase this saving to higher levels.

In the start/stop combi boiler system described above, exhaust temperature is reduced under zero Celsius degree by use of a low capacity compressor. The most important factor in achieving this is to ensure that return water reaches the combi boiler after being significantly cooled down, which is done thanks to the start/stop operating principle. The cooler the return water is, the lower the pressure value needed to be applied by the compressor for transferrin the thermal energy absorbed from discharge air to return water, which reduced energy consumption. Since water sent in the combustion chamber is not very high although it gains heat from the discharge air, high condensation efficiency is achieved in the combustion chamber and amount of water vapour in discharge air is minimised. In this way, there is nearly no frosting problem in the evaporator located in the flue. By switching off the compressor shortly before combustion, formation of frost layers is prevented.

In the start/ stop system, hot water is sent to radiators for a certain time, which means that hot water entering in radiators from the top heats the space in steps. The most important distinction of this system is the reduction in the temperature of return water. Thus, in the start/ stop system, water sent to radiators has higher and return water has lower temperature. The methods and techniques ensuring this are described above. The start/stop operating system ensures high combi boiler efficiency for houses and workplaces. A conventional combi boiler, when operated in the night mode, is unaware of the atmosphere temperature changes, since they generate energy depending on the temperature of the system water. When the weather gets warmer during daytime, the combi boiler cannot promptly reduce the amount of energy generated. In addition, id the combi boiler user in the upper storey notices the rise in weather temperature and decreases combi boiler capacity or switches it off, the combi boiler located in the lower storey would try to compensate energy losses to the upper storey. In this case, electricity cost would increase with unnecessary consumption. This and other similar situations are often observed in particular in calorimeters of central heating systems to cause unfair cost distribution. The user in the lower storey, relying on the thermostatic valves installed to radiators, would not pay attention to consumption and the cost would be distributed unfairly between neighbours at the end of the month. This is a common problem of both combi boiler and calorimeter users. We have started the serial production and marketing of the combi boiler saving device based on the start/stop operating principle, which was described in detail in the application we made to the Turkish patent institution in 2015, in the Turkish market. In addition, by installing a solenoid valve to the socket of these combi boiler saving devices, the tested the start/stop system in combination with calorimeter devices. The combi boiler saving device performed the switching on and off operation on the solenoid valve and as a result of the tests, we observed more realistic and fair consumption costs. Upon this, we decided to produce a new type of calorimeter device by adding the start/stop function. The software developed for the combi boiler saving device with solenoid valves will be used for this calorimeter device after being partly improved. We will have a new type of calorimeter device, combining the conventional calorimeter technology with the start/stop operating software and solenoid valves. The calorimeter will be able to work in combination with a sensor measuring atmosphere temperature and the user will be able have the calorimeter operated depending on atmosphere temperature by use of an adjustment button on the calorimeter. The calorimeter will have the Tl, T2, ... climatic programs with the start/stop operating system. We have developed the most ideal manner of operation for the calorimeter device during the test. By sending hot water to radiators in steps depending on the atmosphere temperature, we have implemented the start/stop operating principle and ensured that cool water is received from the bottom of radiators. As a result of the tests, we are planning to produce the new generation calorimeter device with the software features specifically developed. In this method, we have achieved to decrease the temperature of water arriving the boiler room and exhaust temperature has been also reduced. The calorimeter will be able to control room temperature based on user preferences. The calorimeter device has the same main operating principle with the combi boiler saving device. During the tests, the amount of energy generated depending on atmosphere temperature was sent to radiators in times determined by the combi boiler saving device and it also opened the solenoid valve to send energy. After the energy is sent, the valve was closed by the combi boiler saving device. The time during which the valve stayed closed until the next valve opening was determined by the combi boiler saving device, depending on atmosphere temperature. The calorimeter we are starting to produce can be equipped with additional features to control room temperature data as well. It will enable the user to make settings by use of a button to be placed on the device. The user will be able to remote control the calorimeter with mobile software and set room temperature accordingly. By use of smart phones with GPS feature, the mobile software will activate the system to heat the room when the user is close to the house. This calorimeter device will provide the users with energy saving. Benefits and general properties of the calorimeter device are as follows:

The calorimeter operates in the start/stop system and it is named“start/stop calorimeter”.

The calorimeter control energy transfer to the room by opening and closing the valve.

The start/stop calorimeter reduces the movement of hot water in the concrete structure to reduce heat losses to the structure.

When the start/stop calorimeter is used, hot water enters in radiators at the top and it is discharged from radiators at the bottom at lower temperatures for being sent to the boiler room, which in turn increases condensation efficiency in the boiler flue.

Certain models of the start/stop calorimeter will be equipped with an adjustment button and remote control feature.

Certain models of the start/stop calorimeter will be equipped with temperature sensors to measure atmosphere temperature and/or room temperature.

For invoicing purposes, the data collected by the start/stop calorimeter can be stored in the device or transmitted to a main unit.

The start/stop calorimeter or the main unit may transmit the collected data to the invoicing centre through the internet or the data can be read by use of hand terminals. The invoicing device can be equipped with SIM cards for data transfer.

If the system has a main unit for connecting multiple start/stop calorimeters, data transfer from the unit can be done by use of SIM cards.

Energy consumption amount can be shared with the user on the display of the start/stop calorimeter.

When the start/stop calorimeter is used in combination with the Alimo technique, even higher efficiency gains can be achieved.

Experiments and improvements made on the start/stop combi boiler technology have directed us to the development of another new technology, which is called the HAMITA device. The HAMITA device involves the flue heat transfer systems described above and it was developed to ensure that air is constantly discharged the temperature in low temperatures. Our combi boiler equipped with the flue heat transfer units described above was operating inefficiently when hot tap water was demanded by the user for use in the bathroom and kitchen. Activation of the combustion and the compressor when the tap is opened by the user only for a short while was not an efficient practice. It was impossible to have the desired level of efficiency by having the compressor switched on and off for short durations. This problem and some other technical details led us to develop a new operating system. The combi boiler named Hamita involves all innovations described above. The use of fanpet heat collectors and efficiency gains planned on the water installation enabled us to develop a much more efficient equipment. This highly efficient equipment, called Hamita, is a heater providing continuous combustion during winter, and also a cooler with continuous compressor operation during summer.

The reason why we developed the Hamita device was not it was not possible to involve the compressor for short duration of hot tap water use. When the hamita device is switched on in the beginning of winter, it firstly heats the space by providing heat with the compressor and provides continuous combustion when the weather gets colder. The Hamita devices aims to keep the temperature of return water from fanpets or radiators under 26 Celsius degrees (we are planning to achieve even lower values through technological improvements), and provide higher thermal energy to the user by increasing the temperature of water sent to radiators. In the hamita device, firstly the return water under 26 Celsius degrees is cooled down by the fresh air taken into the combi boiler. Afterwards, the heat absorbed by the compressor from the flue is transferred to the cooled return water. We have managed to reach high efficiency level by decreasing the flue temperature under zero Celsius degree. The Hamita device operates efficiently thanks to the use of thermostatic valves. By increasing and decreasing the temperature and amount of water sent to radiators, the hamita device tries to keep room return water at the desired level. Together with a software similar to the climatic software used in the start/stop operating system, it generates energy like calorimeter devices, based on the return water of water sent to radiators and return water. When the temperature of return water presents a rapid decrease, the hamita device increases flame height and the amount of energy generated. On the other hand, when the temperature of return water presents a rapid increase, it decreases flame height and the amount of energy generated to send water to radiators at lower temperatures. At the same time, it slows down the pump. If the hamita device is fed with the room temperature data, it operates much more successfully on the basis of these data. While it is also possible to integrate an atmosphere temperature measurement sensor to the device, the use of sensors is not a must. With the addition of sensors, the hamita device operates in higher efficiency. As in the start/stop system, water is sent to radiators in higher temperature values. Water is distributed better to radiator, when thermostatic valves are used, although the hamita device is still a successful heating equipment without the use of thermostatic valves. Against potential installation defects, we are recommending the use of thermostatic valves for optimum distribution of water to radiators, since the transfer of water in amount as low as possible provides efficiency gains (the pump used has lower flow rate and capacity when compared to the current condensing combi boilers, and certain models may be equipped with frequency adjusted pumps). In case there is a pressure problem in the water installation, heat distribution among radiators and rooms may become uneven. In order to eliminate this kind of problems, use of thermostatic valves is recommended with the hamita device. If fanpet radiators are used in combination with conventional radiators, there is no frost problem in the hamita device flue. Thus, we also recommend the use of at least one fanpet on the return water line.

Hamita is a continuous combustion device involving the techniques developed for the start/stop combi boiler. All techniques used in the start/ stop combi boiler can be used in various capacities of hamita devices. The hamita device alwy provide low exhaust temperature. In case of hot tap water demand, the three-way valve is activated to provide hot water in low flue temperatures. When the demand is over, the three-way valve starts again to transfer hot water to radiators. In some models, number of heat exchangers may be increased to prevent hating capacity losses for using the energy generated in tap water as well. The hamita device tries to keep return water temperature between 16 and 26 Celsius degrees by use of Alimo techniques. We are aiming to reduce the upper limit to 20 Celsius degrees with technological improvements. Return water arriving the hamita device at 26 Celsius degrees or lower is firstly cooled down by the fresh air taken. Afterwards, the heat absorbed by use of a compressor is transferred back to return water. The mainboard checks the temperature of return water at this point and tries to keep it under 26 Celsius degrees, which ensures high level of condensation in heat exchangers and less frost on the evaporator absorbing flue heat. The continuously operating hamita device has provided more successful results than our start/stop combi boiler, as a result of efficient heat transfer ensured through the continuous operation of the compressor. By adjusting the operating level of the compressor according to return water temperature, exhaust temperature is kept at low level. The main target of the hamita device is to ensure that return water provides high condensation efficiency in the combustion chamber by increasing its temperature with the heat transfer techniques, for the prevention of frosting in the flue. When there Is frost in the flue, the compressor is occasionally operated in low capacity or switched off until frost is removed. General properties of the hamita device are as follows:

It enables the use of a lower capacity circulation pump, when compared to current condensing combi boilers. Operating capacity of the circulation pump is controlled by the mainboard software to adjust the amount of water sent to radiators and keep combustion continuous.

The hamita device operates with continuous combustion, as long as atmosphere temperature is 18 Celsius degrees of lower in models equipped with an atmosphere temperature sensor. This temperature limit can be varied on the software.

If the hamita device is not equipped with a temperature sensor, the software operates the device automatically, depending on the capacity level set on the control panel. Continuous combustion is provided based on the temperature of return water and water sent to radiators. After a certain period of time, it starts to operate like the start/ stop combi boiler to generate energy.

If the hamita device becomes inactivated for any reason, the hot utility water in the tank can be used by the user and the device is activated again when the tank is empty, thanks to the three-way valve and other related components.

The hamita device automatically turns off when the return water temperature gets close to the temperature of water sent to radiators. When all thermostatic valves are closed to prevent water flow to radiators, return water temperature may rapidly increase. This is experienced mostly during transition weather conditions in spring and fall. When such a situation occurs, the hamita device stops operating as described for the start/stop system and switches on the pump again after a certain period of time to measure return water temperature. Simultaneously, atmosphere and/or room temperature are also checked and based on all these data, the climatic program decides if it is necessary to start combustion or not. If necessary, the compressor is switched on and then combustion is started to activate automatic heating.

In case the hamita device is equipped with an atmosphere temperature sensor, the initial stat command is given in the same way with start/stop combi boilers. Firstly, the compressor is switched on and then the pump is activated and combustion is started. (In certain models, when temperature return water is 14 Celsius degrees of higher, only the compressor is activated to absorb the thermal energy of fresh air in the flue, and this absorbed energy is transferred to radiators).

When atmosphere temperature is under 14 Celsius degree (a modifiable value), the hamita device provides continuous combustion and operates for days in the sameway. It is possible to add a feature to ensure that the device is stopped in certain intervals. Certain production and field data are waited for to decide for the addition of this feature.

The hamita device operates continuously for days and even for months under winter conditions, without deactivating the compressor or combustion, other than short periods of time during which flue frost is removed.

The hamita device firstly cools down return water by use of fresh air taken from the atmosphere and then transfers the absorbed energy to the utility water tank and return water.

In addition to the operating principle described in our application made in 2015, in this invention, water temperature is not taken as the basis for starting combustion and combustion and waiting times are defined by the mainboard, based on the climatic program loaded in the mainboard and atmosphere temperature. This is done by the climatic program, based on the atmosphere temperature data, if any. If the combi boiler does not have an atmosphere temperature measurement sensor, the climatic program set starts and stops combustion as a timer, and defines the waiting time, during which the combi boiler does not operate at all. In the combi boiler model with an atmosphere temperature sensor, the mainboard starts combustion and defines waiting time depending on the atmosphere temperature data and controls the amount of thermal energy to be generated on calorie basis. The climatic program loaded in the mainboard determines the waiting time (the time waited before the next combustion is started) based on the atmosphere temperature. Because of this operating principle, we call the combi boiler developed by us“start/stop” combi boiler. When compared to the current condensing combi boiler, our combi boiler transfers hotter water to radiators after each cycle of transfer, the pump is switched off to keep the thermal energy on the upper part of radiators. In result, temperature is kept higher in radiator upper parts, heat losses on installation pipes are reduced and flue temperature is also decreased by ensuring high condensation efficiency. In this system, temperature of return water is lower when compared to the current system. In this method, combi boiler flue temperature is reduced thanks to the flue heat exchanger. The mainboard determines the time when next will start through the control panel connected to the mainboard and/or based on the climatic program set on the control screen. If the mainboard has a sensor to measure atmosphere temperature and/or room temperature, it automatically adjusts the thermal energy generation capacity and regulated all combi boiler functions depending on the climatic changes between day and night time and performs all functions automatically by operating the combi boiler on the start/stop basis. In combi boilers equipped with an atmosphere temperature sensor and/or room thermostat, the mainboard automatically determines combustion time and/or waiting time between two combustion cycles based on temperature variations to ensure high natural gas and electricity saving.

We have developed new features for the start/stop technology specified in our patent application with number 2015/03906 mentioned above. The start/stop operating principle has offered us new fields of application, thanks to which we have managed to significantly reduce exhaust temperature.

In the system subject to our application, by adding the room temperature sensor to the start/stop (including the water circulation pump) principle described in our initial application, the mainboard has been converted into a more successful climatic operation algorithm. In this context, new innovations made after the initial application are as follows:

Operation of the combi boiler in the start/stop system depending on the atmosphere temperature and room temperature data by the mainboard by integrating a room thermostat to the combi boiler.

- Operation of the combi boiler in the start/stop system depending on the atmosphere temperature variations through the automatic activation of the software loaded in the mainboard by integrating an atmosphere temperature sensor to the mainboard. Addition of the hermetic core combi boiler flue to our combi boiler in order to provide heat transfer between fresh air taken and hot ait discharged by the combi boiler.

Addition of the heat exchanger and relate equipment to our combi boiler in order to ensure that return water is cooled down by use of fresh air taken by the combi boiler.

Addition of a compressor for lower exhaust temperature and addition of other equipment to enable heat transfer by the compressor.

In order to reduce exhaust temperature, the software loaded in the mainboard switches on the compressor shortly before starting combustion, and switches off it shortly before stopping combustion

When hot water is demanded, combustion and compressor may remain switched off.

Software was developed to keep return water temperature of the combi boiler low by automatically increasing or decreasing the temperature of water sent to radiators.

In order to increase the efficiency level of the system, the mainboard can be integrated with an atmosphere temperature sensor and/or room thermostat.

Before stopping combustion and then combustion is stopped and the pump is switched off with a delay of seconds. Until the next thermal energy production cycle (until the next combustion), the water circulation pump and other components are switched off by the mainboard and in this system, the combustion start command is given in a very different technique when compared to the current combi boiler operating systems. Combustion starts with low flame height and gradually and quickly increased in line with the command given by the software, Similarly, the combi boiler gradually reduces flame height when combustion is stopped.

While all these features were presented in the application made in 2015, the following features are added to the combi boiler saving device with this application:

The following features have been developed in order to eliminate the problem of delayed hot water transfer to tap for bathroom or kitchen use, when the combi boiler is powered by our saving devices in certain models:

*In order to ensure that the combi boiler saving device to control the combi boiler in the start/stop system through the thermostat connection line on the existing mainboard of the equipment, instead of controlling it through the mains power line, a room temperature measurement sensor has been integrated to our mainboard. Thanks to this, the device measures both atmosphere and room temperature and operates the combi boiler in the start/stop system. In addition, the combi boiler saving device can be installed on the room thermostat inlet, in addition to the combi boiler power line. The combi boiler can be connected to the saving device both on the power line and the on/off room thermostat line. Shortly before the electric power to the combi boiler is cut, the device stops combustion with a command given through the room thermostat socket and only after this power is cut. When it receives related command via the water socket, the device feeds power to the combi boiler, but if radiator heating was not demanded by the user, it keeps the combi boiler in the summer operation mode via the room thermostat socket.

*If the Combi Boiler is used in a system with a water sensor, when the tap is opened and then closed, our combi boiler saving device continues to feed power to the combi boiler for a while. In result, while hot water is used in the bathroom is kitchen, there is no delay in the transfer of hot water to the tap when the tap is opened and closed in short intervals, which ensures water savings during winter months. This software feature has been added in the combi boiler saving device. When hot water is demanded by the user, although power is fed to the combi boiler, the room thermostat is in off position and the combi boiler does not activate the winter operating mode, if room temperature is in the demanded range.

* Some of our models allow the integration of certain software features to enable remote control by use of mobile applications. When our GPS integrated mobile application is used, the application actives the combi boiler in the start/stop system and tries to reach the targeted room temperature, depending on the distance of the user to the combi boiler.

In the start/stop combi boiler system, combustion and pump operation are simultaneous, which means that combustion starts and stops together with the water pump. Combustion command does not depend on the temperature of water passing through the combi boiler. The mainboard developed performs all functions of electronic cards used in current combi boilers and in addition, it monitors atmosphere temperature and room temperature to calculate the amount of energy required to be generated by the combi boiler. The most importance distinctions here are as follows:

Combustion and pump operation start and stop in a synchronized manner. The waiting time after combustion is variable when an atmosphere temperature sensor and/or a room temperature sensor is used.

In the start/stop system, starting of combustion does not depend on the temperature of water passing through the combi boiler.

The main objective of the start/stop system is to keep the temperature of water sent to radiators high, while temperature of water returning to the combi boiler is as low as possible.

The mainboard measures the amount and temperature of water sent to radiators and also temperature of return water to control the amount of energy generation accordingly. The user may change the energy program on the control panel. The program set functions depending on the atmosphere temperature and/or room temperature. Based on the atmosphere temperature, the active program automatically control the amount of energy to be generated and then the waiting time, and it also calculates combustion time by measuring atmosphere temperature.

In our combi boiler model without any temperature sensor, the user increases or decreases the working and waiting times by turning the capacity button. In this combi boiler type, the mainboard controls the amount of energy to be generated together with a timer program. Waiting time is defined by the user through program selection and combustion starts at the end of every waiting period. Depending on the temperature of return water, temperature of water sent to radiators is automatically adjusted by the combi boiler mainboard.

Some climatic programs keep the amount of energy to be generated constant and the combi boiler is controlled by the mainboard in terms of the waiting time after combustion.

When the mainboard (electronic card) is integrated to the mainboard our solutions accommodating the related software are installed on the mainboard, the following operating logic is implemented: Shortly after the required amount of energy is generated and combustion is stopped, the circulation pump is switched off, which extends the economic life of the equipment by minimising the formation of lime layers and corrosion on the internal surface of the burner in the combustion chamber. Thanks to the modulation feature of the mainboard, flame height is gradually increased I approximately 12 seconds, or decreased during the starting and stopping of combustion respectively. Thanks to this modification, expansion and contraction rates of combi boiler internal parts have been reduced.

However, as another the innovation made on the combi boiler mainboard software operating system, the combi boiler saving device, which can be installed on the mains power line independent from the combi boiler or on the atmosphere connection or through a special socket for existing combi boilers, completely cuts electricity feeding to the combi boiler to operate the equipment compatible with the program, or it can be installed through the room thermostat socket for certain combi boiler models to operate the equipment in the start/stop system. As an alternative, it can be connected on both the power line and room thermostat socket. In addition, when a button on the device is pressed, it feeds continuous electricity to the combi boiler for a period, but checks the combustion conditions by use of temperature sensors through the room thermostat. When the conditions are not suitable, it keeps the combi boiler in the summer operation mode through the room thermostat socket to prevent hot water transfer to radiators. This feature is added on the combi boiler saving device as an option to enable users to use hot tap water during the year. Besides, the device has an on/off button that can be used to completely deactivate it to feed continuous electricity to the combi boiler. In addition, a water flow sensor is installed to the mains water inlet. The data sent by the water flow sensor are read by the combi boiler saving device continues to feed electricity to the combi boiler until a second command is given, which means the tap is closed. Some models continue to feed electricity to the combi boiler for a while after the tap is closed. For existing combi boilers that are not suitable for the use of a water flow sensor, the device will have a button to function as a time-delay relay. Our products containing the mainboard, as shown in the drawings, can be also installed on newly produced combi boilers and ensure energy saving by defining combustion and waiting times depending on the data sent by the atmosphere temperature sensor of the combi boiler. Thanks to the abovementioned software implementation, we have made improvements on certain combi boiler components and developed new combi boiler components to increase efficiency. These components can be installed separately or in combination, depending on the capacities of combi boiler to be produced.

- Our alternative implementations developed for reducing exhaust temperature: Bithermic heat exchanger for higher condensation efficiency. We have developed two different bithermic heat exchangers for this purpose.

1- This heat exchanger model is installed in the combi boiler in the same direction with gravity force. Heating unit of this bithermic heat exchanger is located on the top part. Hot water moves upwards in the spring shaped pipes surrounding the combustion chamber that contains the hot air mass generated by the he heater and absorbs thermal energy. Before reaching the combustion area, this water mass passes in the spiral shaped structure under the lower part of the combustion chamber and rises in the pipe by gaining heat. The hot water heating the return water gets cooler move downwards in the spiral shaped line and the heated hot water passes in the spiral shaped structure to reach the combustion chamber. The spiral shaped structure ends at the entrance of the combustion chamber and the rising hot water absorbs thermal energy around the burner and moves to radiators by leaving the combustion chamber from the top. The hot air mass in the combustion chamber enters at the top of the spring shaped structure to heat the return water and it cools down while moving downwards. Thus, the hot ait coming from the burner moves downwards in a spiral route and loses heat. Inside this air line, there is the water line to carry the water moving upwards by gaining heat. In this method, which makes use of gravity force and advantages of density, air mass is cooled down and sent downwards. Drawing of this heat exchanger design is submitted in our application as a sample. 2- This heat exchanger model is installed in the combi boiler in the same direction with gravity force. Under the combustion chamber that contains the hot air mass generated by the he heater, thin bithermic heat exchangers are placed downwards in layers, on top of each other. Heat exchangers are surrounded by the insulated combustion chamber. Heat exchangers were designed for being assembled to each other easily. In this implementation, hot ait in the combustion chamber gradually cools down and sinks downwards, while the water mass gradually gains heat and raises as a result of the decrease in density. Hot water, which is heated by use of plate type heat exchangers, arrives to the burner division are moves around the burner to raise, and leaves the combustion chamber at the top to be sent to radiators. In this method, which makes use of gravity force and advantages of density, air mass is cooled down and sent downwards. Drawing of this heat exchanger design is submitted in our application as a sample.

B) New hermetic core combi boiler flue.

The flow line of the hot air mass entering in this flue is covered with a fill material with poor heat conduction properties and by being directed by the fill material, hot air moves to the thin channels around the pipe. After contact with hot air, outer surface of these thin channels transfer the thermal energy absorbed from hot air to the fresh air taken. Thanks to this thin heat exchanger plates contacting both the fresh air taken and hot air discharged by the combi boiler, thermal energy is transferred from discharged air to fresh air. Along the flue, there are cuts which prevent heat transfer to make the flue more efficient. There are seals placed on this cuts to prevent the mixture of fresh air with discharge air. The flue structure developed by us increases the heat transfer surface thanks to thin heat exchanger plates. Air moving through these thin plates rapidly loses heat towards the outlet, while the fresh air taken into the flue gradually gains heat when moving towards the combi boiler. Hot water is linearly blown outside through the heat exchanger plates. There are suction channels to take fresh air at the end of the flue. This flue design ensures heat transfer between incoming and discharged air masses.

Thermal bridge for the reduction of exhaust temperature. This implementation has two different types.

A) Cooling down of the hot return water by use of the fresh air taken into the combi boiler.

Firstly, return water is cooled down by use of the fresh air taken by the combi boiler. Afterwards, it is sent to the combustion chamber for high level of condensation. After reaching the highest temperature, water is sent to radiators. This technique has provided high level of efficiency. In this technique, fresh air is directed to a heat exchanger developed to cool down return water. In order to prevent that residue accumulation occurs in the heat exchanger in time, fresh air is filtered. The filter can be added to the combi boiler as an option, based on the conditions of use. Fresh air cools down return water by passing through the heat exchanger in which return water flows. Then, return water is directed to the heat exchanger placed in the division where toxic gasses from the combustion chamber are discharged to. Thanks to the cooled down return water, high amount of energy is absorbed from discharge air in the flue. After reaching the desired temperature, water is sent to radiators. The fresh air preheated in the flue gains heat while it cools down return water and then it is sent to the combustion chamber together with natural gas. This technique offers very high condensation efficiency. If this combi boiler is to be used in very cold weather, it is required to add anti -freezing agent in water to prevent freezing. Otherwise, the fresh hair taken into the combi boiler may remain under zero Celsius degrees despite preheating in the flue. In very cold weather conditions, preheated fresh air meets with return water at around -40 Celsius degrees and it may freeze return water in the heat exchanger. In order to eliminate this risk, freezing temperature of water must be decreased by adding a freezing agent. The start/stop technique has enabled us to develop the abovementioned innovations and try new techniques to achieve high efficiency levels. B) The technique in which energy is recovered from hot discharge air by use of a compressor can be implemented in three different methods in combi boilers.

- This system makes use of the advantages offered by the start/stop system. In this system, the compressor is switched on shortly before the circulation pump to increase evaporator efficiency. Afterwards, the combi boiler starts combustion together with the propeller and circulation pump.

- When combustion starts, the whole system works and exhaust temperature is very significantly reduced.

The method explained here is operated in an infinite loop and exhaust temperature is reduced to increase energy efficiency of the combi boiler. 2- Thermal energy contained in the discharge air is absorbed and transferred to the utility water and then to the cool return water to ensure energy saving. By reversing this process, the natural gas combi boiler can be converted to a cooling device. Details and operating principles of this process are as follows:

- By use of a compressor and an evaporator, thermal energy contained in the discharge air is absorbed.

- When combustion starts, the whole system works and exhaust temperature is reduced to around zero Celsius degree and even to minus temperatures in certain models, as a result of which significant energy efficiency is obtained. - Thanks to the preheating of utility water, the combi boiler always contains some amount of hot water. This way, waste of water resulting from delayed combustion in hot water use from the tap is reduced. Current combi boilers wait for a while before starting combustion when the tap is opened, which causes waste of water. This technique eliminates this problem.

- The three-way valve is activated during hot water use from the tap and the whole thermal energy absorbed from the flue is transferred to the utility water without switching off the compressor. When hot water is demanded while the radiator heating function is deactivated, the compressor is not activated.

- By reversing this process explained above, our combi boiler can has been added the feature to cool the space. In summer months, thermal energy of warm return water is absorbed and water is sent back to radiators after its temperature is reduced between 21 and 17 Celsius degrees. With this process, the combi boiler operates as a cooler in summer months. In this process, based on the data sent by combi boiler sensors, the propeller, circulation pump and the compressor added to the combi boiler always switch on and off together by functioning as a start/stop unit.

3) By use of the compressor, thermal energy contained in the discharge air is absorbed and transferred to the utility water tank, and then to the fresh air taken from the atmosphere.

Thermal energy discharged by the combi boiler is absorbed by use of the compressor and evaporator. Recovered thermal energy is firstly used to heat the utility water and as the utility water gets hotter, thermal energy is transferred to the cold fresh air mass by use of the condenser. In certain techniques, hot air mass from the combi boiler is sent to an external unit equipped with an evaporator and a fan. Thermal energy is absorbed by this external unit and firstly transferred to the utility water tank and then to the fresh air mass taken in the combi boiler. In certain models, thermal energy absorbed by the external unit is transferred to return water that was cooled down by fresh air. This technique increases the operating efficiency of the compressor.

Thermal energy of the hot air mass discharged to the atmosphere is absorbed by use of a compressor. Absorbed energy is firstly transferred to utility water tank and secondly to the return water which has been cooled down by fresh air taken from the atmosphere. In result,

Risk of freezing in the evaporator connected to the compressor is very low, since return water is cooled down in the flue,

In the combi boiler equipped with this technology, the compressor switched on shortly before the end of the waiting time, before combustion starts and it is switched off shortly before combustion is stopped, which eliminates prevents on the evaporator.

One of the most important problems of combi boilers is resetting and the resulting deactivation of the heating function, caused by loss of water in the system. With a software feature developed by us, water replenishment in the combi boiler is automatically performed. The amount of water added does not exceed a certain amount in litres. The amount of water to be added is calculated by the mainboard, in consideration of the last water replenishment date and replenishment is performed automatically. When the amount of water added reaches the amount defined in the software, the combi boiler gives audio warning to the user and in certain models, it sends information to the mobile software. When the amount of water added is excessive, the mainboard closes all solenoid valves located at all system inlets and outlets and takes the combi boiler to the safety mode. If there is risk of freezing, it switches on the combi boiler for a short time. This way, the risk of flooding is minimised.

We have tried some techniques on the water installation during the development of the start/ stop system in order to improve the performance of compressor and heating even more. In result, we have developed the optimum water installation model, as a result of which the combi boiler started to operate in higher efficiency.

Properties of this method, called the Alimo technique, are listed as follow:

1- The hot water installation transferring water from the combi boiler to radiators should be covered with insulating materials and pipes with good insulation properties should be used.

2- Radiator sizes should be increased by at least 20% when compared to the radiators used for conventional condensing combi boilers.

3- Return water line should be passed through hallways in order to transfer any lost thermal energy to the concrete floor.

4- The use of secondary radiators called Fanpet, to which return water pipes are connected, provides significant level of efficiency gain.

5- Return water lines should be installed in the longest route possible.

6- Return water line should pass through the floor of the common use areas of the house or other space heated and the Alimo floor collector should be used. 7- Alimo heat transfer technique: This is the general name given for the products and techniques developed for sending water to radiators with minimum loss of heat and ensure fast loss of heat in return water. General principles of this technique are described above. Two different products have been developed by us, in addition to the abovementioned techniques. a) In newly constructed houses, hot water lines reaching radiators are insulated against heat loss. In order the ensure that return water transfers its whole thermal energy to the floors of common use areas, return water line is passed through the longest route. A special apparatus developed by us is used in order to ensure that thermal energy is completely transferred to the floor concrete along hallways and in the kitchen. If possible, return water pipes are brought together in a collector before the said apparatus and the return water pipes are connected to the Alimo floor collector in s single line. If it is not possible to bring all lines together, one Alimo floor collector is connected to each return water line. The line from the collector is laid up to the combi boiler in the hallway and kitchen floor. This apparatus has left and right legs and it is made of stainless steel. The special technique used in the design of legs ensures high level of heat transfer. Additionally, pipes with high heat transfer properties are used for the return water line in newly constructed houses. Thanks to these techniques, return water temperature is reduced under 20 Celsius degrees. b) Alimo Fanpet is used in previously constructed houses and workplaces. Alimo fanpet is a new generation radiator being developed by our team. On the inlet of this radiator, there is a sensor detecting water flow, which sends information to the electronic circuit reading the flow data. There are fans connected to the circuit and fans are operated only when there is water flow. Alimo fanpet is installed on the return water line all return water is passed through one or more fanpets. Fanpet sends command to the electronic card via sensors detecting water flow. As long as there is water flow, electric fans are automatically operated for fast heat transfer from return water. These fanpet radiators can be used as radiators in many spaces of newly constructed houses. In particular, in rooms or spaces having“Italian style” windows, radiators are not placed under windows. Instead, they are placed in other points of the room. In winter months, hot and cold air meeting on the glass causes condensation on the glass as a result of hot and cold air meeting on the glass. Drops caused by condensation cause damage on the wall behind the radiator and wooden floor under the radiator. Thin Alimo Fanpets are placed as second radiators under windows to eliminate condensation and water drops on the glass. Return water coming from the primary radiator of the room is passed through fanpet and it cools down there. Return water leaving fanpet is completely cooled down by use of the Alimo installation technique and it reaches the combi boiler after losing a high amount of thermal energy. Thanks to fanpets, the cold air mass flowing through walls and windows to room floor is prevented and the temperature difference between room ceiling and floor is reduced to ensure a healthy environment. The fanpet technology can be offered as portable equipment for being installed under radiators. This way, users may have both a combi boiler heating system and a cooling system for summer months without replacing radiators.

Our start/stop combi boiler making use of the abovementioned techniques generate the same level of heating with current condensing combi boilers that control combustion based on water temperature, by consuming 20% less energy.

In the start/stop combi boiler system described above, exhaust temperature is reduced under zero Celsius degree by use of a low capacity compressor. The most important factor in achieving this is to ensure that return water reaches the combi boiler after being significantly cooled down, which is done thanks to the start/stop operating principle. The cooler the return water is, the lower the pressure value needed to be applied by the compressor for transferrin the thermal energy absorbed from discharge air to return water, which reduced energy consumption. Since water sent in the combustion chamber is not very high although it gains heat from the discharge air, high condensation efficiency is achieved in the combustion chamber and amount of water vapour in discharge air is minimised. In this way, there is nearly no frosting problem in the evaporator located in the flue. By switching off the compressor shortly before combustion, formation of frost layers is prevented. In the start/ stop system, hot water is sent to radiators for a certain time, which means that hot water entering in radiators from the top heats the space in steps. The most important distinction of this system is the reduction in the temperature of return water. Thus, in the start/ stop system, water sent to radiators has higher and return water has lower temperature. The methods and techniques ensuring this are described above. The start/stop operating system ensures high combi boiler efficiency for houses and workplaces. A conventional combi boiler, when operated in the night mode, is unaware of the atmosphere temperature changes, since they generate energy depending on the temperature of the system water. When the weather gets warmer during daytime, the combi boiler cannot promptly reduce the amount of energy generated. In addition, id the combi boiler user in the upper storey notices the rise in weather temperature and decreases combi boiler capacity or switches it off, the combi boiler located in the lower storey would try to compensate energy losses to the upper storey. In this case, electricity cost would increase with unnecessary consumption. This and other similar situations are often observed in particular in calorimeters of central heating systems to cause unfair cost distribution. The user in the lower storey, relying on the thermostatic valves installed to radiators, would not pay attention to consumption and the cost would be distributed unfairly between neighbours at the end of the month. This is a common problem of both combi boiler and calorimeter users. We have started the serial production and marketing of the combi boiler saving device based on the start/stop operating principle, which was described in detail in the application we made to the Turkish patent institution in 2015, in the Turkish market. In addition, by installing a solenoid valve to the socket of these combi boiler saving devices, the tested the start/stop system in combination with calorimeter devices. The combi boiler saving device performed the switching on and off operation on the solenoid valve and as a result of the tests, we observed more realistic and fair consumption costs. Upon this, we decided to produce a new type of calorimeter device by adding the start/stop function. The software developed for the combi boiler saving device with solenoid valves will be used for this calorimeter device after being partly improved. We will have a new type of calorimeter device, combining the conventional calorimeter technology with the start/stop operating software and solenoid valves. The calorimeter will be able to work in combination with a sensor measuring atmosphere temperature and the user will be able have the calorimeter operated depending on atmosphere temperature by use of an adjustment button on the calorimeter. The calorimeter will have the Tl, T2, ... climatic programs with the start/stop operating system. We have developed the most ideal manner of operation for the calorimeter device during the test. By sending hot water to radiators in steps depending on the atmosphere temperature, we have implemented the start/stop operating principle and ensured that cool water is received from the bottom of radiators. As a result of the tests, we are planning to produce the new generation calorimeter device with the software features specifically developed. In this method, we have achieved to decrease the temperature of water arriving the boiler room and exhaust temperature has been also reduced. The calorimeter will be able to control room temperature based on user preferences. The calorimeter device has the same main operating principle with the combi boiler saving device. During the tests, the amount of energy generated depending on atmosphere temperature was sent to radiators in times determined by the combi boiler saving device and it also opened the solenoid valve to send energy. After the energy is sent, the valve was closed by the combi boiler saving device. The time during which the valve stayed closed until the next valve opening was determined by the combi boiler saving device, depending on atmosphere temperature. The calorimeter we are starting to produce can be equipped with additional features to control room temperature data as well. It will enable the user to make settings by use of a button to be placed on the device. The user will be able to remote control the calorimeter with mobile software and set room temperature accordingly. By use of smart phones with GPS feature, the mobile software will activate the system to heat the room when the user is close to the house. This calorimeter device will provide the users with energy saving. Benefits and general properties of the calorimeter device are as follows: a) The calorimeter operates in the start/stop system and it is named“start/stop calorimeter”.

b) The calorimeter control energy transfer to the room by opening and closing the valve.

c) The start/stop calorimeter reduces the movement of hot water in the concrete structure to reduce heat losses to the structure.

d) When the start/stop calorimeter is used, hot water enters in radiators at the top and it is discharged from radiators at the bottom at lower temperatures for being sent to the boiler room, which in turn increases condensation efficiency in the boiler flue.

e) Certain models of the start/stop calorimeter will be equipped with an adjustment button and remote control feature.

f) Certain models of the start/stop calorimeter will be equipped with temperature sensors to measure atmosphere temperature and/or room temperature.

g) For invoicing purposes, the data collected by the start/stop calorimeter can be stored in the device or transmitted to a main unit.

h) The start/stop calorimeter or the main unit may transmit the collected data to the invoicing centre through the internet or the data can be read by use of hand terminals.

i) The invoicing device can be equipped with SIM cards for data transfer. j) If the system has a main unit for connecting multiple start/stop calorimeters, data transfer from the unit can be done by use of SIM cards.

k) Energy consumption amount can be shared with the user on the display of the start/stop calorimeter.

l) When the start/stop calorimeter is used in combination with the Alimo technique, even higher efficiency gains can be achieved.

The reason why we developed the Hamita device was not it was not possible to involve the compressor for short duration of hot tap water use. When the hamita device is switched on in the beginning of winter, it firstly heats the space by providing heat with the compressor and provides continuous combustion when the weather gets colder. The Hamita devices aims to keep the temperature of return water from fanpets or radiators under 26 Celsius degrees (we are planning to achieve even lower values through technological improvements), and provide higher thermal energy to the user by increasing the temperature of water sent to radiators. In the hamita device, firstly the return water under 26 Celsius degrees is cooled down by the fresh air taken into the combi boiler. Afterwards, the heat absorbed by the compressor from the flue is transferred to the cooled return water. We have managed to reach high efficiency level by decreasing the flue temperature under zero Celsius degree. The Hamita device operates efficiently thanks to the use of thermostatic valves. By increasing and decreasing the temperature and amount of water sent to radiators, the hamita device tries to keep room return water at the desired level. Together with a software similar to the climatic software used in the start/stop operating system, it generates energy like calorimeter devices, based on the return water of water sent to radiators and return water. When the temperature of return water presents a rapid decrease, the hamita device increases flame height and the amount of energy generated. On the other hand, when the temperature of return water presents a rapid increase, it decreases flame height and the amount of energy generated to send water to radiators at lower temperatures. At the same time, it slows down the pump. If the hamita device is fed with the room temperature data, it operates much more successfully on the basis of these data. While it is also possible to integrate an atmosphere temperature measurement sensor to the device, the use of sensors is not a must. With the addition of sensors, the hamita device operates in higher efficiency. As in the start/ stop system, water is sent to radiators in higher temperature values. Water is distributed better to radiator, when thermostatic valves are used, although the hamita device is still a successful heating equipment without the use of thermostatic valves. Against potential installation defects, we are recommending the use of thermostatic valves for optimum distribution of water to radiators, since the transfer of water in amount as low as possible provides efficiency gains (the pump used has lower flow rate and capacity when compared to the current condensing combi boilers, and certain models may be equipped with frequency adjusted pumps). In case there is a pressure problem in the water installation, heat distribution among radiators and rooms may become uneven. In order to eliminate this kind of problems, use of thermostatic valves is recommended with the hamita device. If fanpet radiators are used in combination with conventional radiators, there is no frost problem in the hamita device flue. Thus, we also recommend the use of at least one fanpet on the return water line.

a) It enables the use of a lower capacity circulation pump, when compared to current condensing combi boilers.

b) Operating capacity of the circulation pump is controlled by the mainboard software to adjust the amount of water sent to radiators and keep combustion continuous.

c) The hamita device operates with continuous combustion, as long as atmosphere temperature is 18 Celsius degrees of lower in models equipped with an atmosphere temperature sensor. This temperature limit can be varied on the software.

d) If the hamita device is not equipped with a temperature sensor, the software operates the device automatically, depending on the capacity level set on the control panel. Continuous combustion is provided based on the temperature of return water and water sent to radiators. After a certain period of time, it starts to operate like the start/ stop combi boiler to generate energy.

e) If the hamita device becomes inactivated for any reason, the hot utility water in the tank can be used by the user and the device is activated again when the tank is empty, thanks to the three-way valve and other related components.

f) The hamita device automatically turns off when the return water temperature gets close to the temperature of water sent to radiators. When all thermostatic valves are closed to prevent water flow to radiators, return water temperature may rapidly increase. This is experienced mostly during transition weather conditions in spring and fall. When such a situation occurs, the hamita device stops operating as described for the start/stop system and switches on the pump again after a certain period of time to measure return water temperature. Simultaneously, atmosphere and/or room temperature are also checked and based on all these data, the climatic program decides if it is necessary to start combustion or not. If necessary, the compressor is switched on and then combustion is started to activate automatic heating.

g) In case the hamita device is equipped with an atmosphere temperature sensor, the initial stat command is given in the same way with start/stop combi boilers. Firstly, the compressor is switched on and then the pump is activated and combustion is started. (In certain models, when temperature return water is 14 Celsius degrees of higher, only the compressor is activated to absorb the thermal energy of fresh air in the flue, and this absorbed energy is transferred to radiators).

h) When atmosphere temperature is under 14 Celsius degree (a modifiable value), the hamita device provides continuous combustion and operates for days in the sameway. It is possible to add a feature to ensure that the device is stopped in certain intervals. Certain production and field data are waited for to decide for the addition of this feature.

i) The hamita device operates continuously for days and even for months under winter conditions, without deactivating the compressor or combustion, other than short periods of time during which flue frost is removed.

j) The hamita device firstly cools down return water by use of fresh air taken from the atmosphere and then transfers the absorbed energy to the utility water tank and return water.
