The invention relates to a power system, in particular to indoor water heating systems, and is intended for use in boiler heating systems, can be used in apartments of 5 pax citizens.

It is known, for example, to have closed water to a district heating system, including two-pipe heating mains to which 10 heat consumers are connected — heating systems and hot water systems. The latter are connected to heating networks in a parallel, serial or mixed circuit.15

A drawback of this analogue is that only partly heat from the return network water is not used or is used to heat water in the hot water supply system.

The closest technical solution to the proposed technical solution is a water heating and hot water supply system (adopted for the prototype), containing a water boiler connected through an equalization tank with a direct pipeline, heating devices connected by connecting to direct and return pipelines, the last of which is connected to the 30 boiler, mixers with cold and hot water taps, connected to cold and hot water pipelines, the first of which is connected to the equalizing bar chku, through the shutoff valve and ball valve 35 pan.

A disadvantage of the prototype is that the surge tank is large because a large supply of water is required when using the bathtub. Another 40 disadvantage of the prototype is that it is fed with cold water before the water boiler, as a result, on the one hand, the wall of the water boiler is red-hot by combustion products, and on the other hand, 45 is sharply cooled by the supplied cold water, which will lead to deformation metal and the formation of microcracks in the walls of the water boiler.

A third disadvantage of the prototype is that the hot water supplied to the drain taps in the kitchen and bathroom stagnates in the pipes, i.e. First, stagnant water must be drained, and only then will water go 55 hours, which leads to unnecessary water consumption.

The aim of the invention is to save fuel and improve comfort in summer.

This goal is achieved by the fact that the water heating system and hot water supply comprising a water boiler connected through a surge tank with a straight pipe, heating devices connected by pipelines to the direct and return pipes, connected to cold and hot water pipelines , the last of which is connected to the boiler, mixers with taps of cold and hot water, connected to pipelines of cold and hot water, the first of which is connected to the surge tank, through a shut-off valve An and a ball valve are made in the form of heating devices connected by jumpers to each other and to the hot water pipeline, shutoff elements are installed on the underwater, before and after the heating devices, air plugs are installed on the jumpers between the heating devices, the hot water pipeline is connected to the return pipe, and the equalization tank is equipped with a relief valve and a nozzle with a shut-off element.The properties of water heating systems and hot water supply coincide in both the known and the declared scoop NOSTA, but as a result of administration to the claimed jumper system connected between the heaters, hot water is pressed out of the heating devices for consumer needs, as in the prior art have this property.

The drawing shows a system of water heating and hot water supply.

The system consists of jumpers 1, 2, 3, the last of which is connected to the shut-off bodies 4, 5, 6, 7, which form the mixers 8 and 9, the shut-off bodies 5 and 7 are connected to the cold water pipe 10, which is branched through a shut-off valve 11 it is connected to a surge tank 12, in which a nozzle is installed to remove air 13 with a shut-off element 14 inserted into it and supplying water from the water boiler 15 to a straight pipe 16, which is connected via inlets into which shut-off valves 17 , 18, 19 is connected to heating devices 20; 21, 22, which through the outlets in which the stopcocks 23,24,25 are inserted are connected to the return pipe 26, from which the drain shut-off element 27 leaves, the shut-off bodies 28 and 29 serve to remove the air plug from the heating devices, 30 - the relief valve, 31 - the shut-off valve organ.

The device operates as follows.

Through the open shut-off member 11. the cut-in pipe 10, cold water fills the entire heat supply system. In this position, the water boiler is heated 15. The system proposed by the author, shown in the figure, is designed for a three-room apartment with a kitchen and a bathroom, heating devices 20, 21, 22 are located in each of the three rooms (not shown). A person can use hot water from the heating system. To do this, open the locking elements 4 or

6. Hot water can be mixed with cold water by opening the locking elements 5 or

7. Air is removed from the system through the nozzle 13 and the open shut-off element 14. If the amount of hot water for consumption is not enough, the shut-off bodies 17, 18, 23, 24, 25 are closed. When the shut-off elements 4 or 6 are open, hot water is forced through the open shut-off element 19 into the heaters 20, 21, 22 connected by jumpers 1 and 2. In this position, the shut-off bodies remain after the end of the heating season.

It is well known that heaters have an infinitely large cooling surface and heat from water is effectively transferred through heaters in the atmosphere. However, if the atmospheric air is warmer than water, then the water in the radiators is heated to a temperature equal to the atmosphere. A person can use water heated by atmospheric air for needs, which is the main idea of the author. For example, the temperature on a summer day on the street is + 22 ° C, the apartment is the same, therefore, in the heating system, the water temperature will be about + 22 ° C. Such water can be used to wash in the shower or in the bathtub, the amount of water in the radiators 20, 21, 22, straight pipe 16, jumpers 1, 2, 3 is enough to wash in the shower or take a bath. Ordinary drinking water coming from pipeline 10 (which is thermally insulated and passes, as a rule, underground so that it does not freeze in winter), you will not wash yourself in the bathroom or shower, because its temperature is +5 - + 10 ° С. Such water must be heated and time and fuel wasted on this matter.

If we take into account that the average summer temperature in the middle zone of Russia is + 20 ° С, then the water + 20 ° С squeezed out of heating devices 20, 21, 22 can be washed in the shower and in the bathroom all summer without spending

heating water for these purposes fuel. With the onset of the heating season, the locking elements 17, 18, 23, 24, 25 open and the heating system operates as usual. The locking bodies 17, 18, 19, 23, 24, 25 can regulate the temperature in the heating devices or turn them off completely. For example, if there is no need to heat the middle room, then the locking

bodies 18 and 24 are closed and the heater 21 is turned off. Through the shutoff members 28 and 29, air is removed from the heaters 21 and 22. Through the shutoff member 27, water can be drained from the system.

having previously closed the shut-off element 11. The relief valve 30 is activated when the water pressure increases above normal. The jumper 3 connected to the locking elements 4 and 6, branched, the second end through the locking body 31 is connected to the return pipe 26. After the end of the heating season with the closing of the locking bodies 17, 18, 23, 24, 25, the locking body 31 also closes. which opens with the onset of the heating season. If the number of rooms in the apartment is more or less than three, then the heating devices will be respectively more or less than three.

The effectiveness of the proposed is that in summer, comfortable conditions are improved, fuel is saved, the life of the boiler is increased, and the reverse can be washed effectively

the pipeline from dirt and rust, the surge tank has a small size in comparison with the prototype.
