The implementation of the invention

The outdoor condensing water-heating installation consists of a thermally insulated body 1, inside of which a vertical thermally insulated boiler 2 with a gas burner 3, a chimney 4 is installed, while a heat exchanger 6 made of corrugated stainless steel pipe is installed in the smoke collector 5 of the boiler 2, and installed in the jacket of the boiler 2 the second heat exchanger 7 is made of corrugated stainless steel pipe, and the heat exchangers 6 and 7 are connected in series, a shut-off valve 8 and a valve 9 for water from the heat exchanger 6, the same taps are installed on the outlet pipe of the heat exchanger 7. The smoke collector 5 contains a condensate pipe 10, while each gas pipe 11 of the gas pipe part of the boiler 2 contains a turbulator 12, suspended from the pipe edges 11 by an arm 13 to which a protective washer is attached 14, and on the front side of the installation there is a stepped gas burner 15 with regulators 16 and 17 connected to thermostats 18 and 19 and a temperature gauge 20; in the upper part of the installation, a filler pipe 21 is installed, closing first spring-loaded cap 22 and the surge tank 23 is connected a tube 24 with a filling nozzle 21.

Condensation hot water installation outdoor placement works as follows.

Using the filler pipe 21, the boiler 2 is completely filled with water or non-freezing liquid, and liquid is added to the expansion tank 23 until the tube 24 is immersed in the liquid, the filler pipe 21 is closed by a spring-loaded cover 22, the taps 9 are opened and the taps 9 are opened, the burner 15 is lit and heated boiler 2 according to the temperature gauge 20 to the required value (60-70 ° C), adjust the thermostats 18 and 19 to turn off the controllers 16 and 17 with a small temperature difference of 5-10 ° C. A faucet (not shown) for the hot water flow in the building is opened, cold water from the water supply through taps 8 and 9 enters the heat exchanger 6, heats up and passes to the heat exchanger 7, immersed in the heat transfer medium of the boiler 2, where it is heated to the set temperature and through the taps 8 and 9 enters the consumer network of the serviced building (not shown), due to the fact that the temperature of cold water is usually 5-15 ° C, which is significantly lower than the dew point of flue gases (approximately 56 ° C) on the surfaces of the heat exchanger 6 condensate water vapor s, drops of which drip onto the tube plate of the gas pipes 11, the protective washers 14 and the condensate drain pipe 10 are removed from the smoke collector 5. The flue gases from combustion in the burner 3 rise upward, swirling in the gas pipes 11 using turbulators 12, through the gap between the protective washer 14 and the edge of the pipe 11, determined by the diameter of the bracket 13, enter the smoke collector 5 of the boiler 2, where they wash the heat exchanger 6 and are removed by the chimney 4 into the atmosphere. When heating boiler 2, the coolant, expanding through the filler pipe 21, is poured into the expansion tank 23 through the pipe 24. When the burner 15 of the boiler 2 is turned off, the coolant from the expansion tank 23 through the pipe 24 is again sucked into the boiler 2, as happens with the coolant of the internal combustion engine through the radiator cap. With a partial analysis of hot water, the temperature of the coolant in the boiler 2 increases and the thermostat 18 gives a signal to turn off part of the burner power through the regulator 17. When the water is stopped, the temperature of the coolant in the boiler 2 again increases and the thermostat 19 sends a signal to turn off the burner 15, which goes into mode standby, only the ignitor (not shown) is lit. When the water recovery is resumed, the regulator 16 is sequentially turned on by the command of the thermostat 19, and then the regulator 17 by the command of the thermostat 18, the entire power of the heating pad 15 is used to prepare hot water with an efficiency greater than 100% due to the constant capture of energy during condensation of water vapor.

Since all elements of the boiler located below the smoke collector 5 are protected from condensation, the boiler 2, except for the smoke collector 5 and heat exchangers 6 and 7, are made of traditional materials, which reduces the cost of the installation and makes it affordable for buyers of the Russian Federation, and automatic provision It is difficult to underestimate the hot water of housing and communal services and the population without heating mains, boiler houses, maintenance staff.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- reduction in the cost of installation;

- increased efficiency due to the additional capture of energy during condensation of water vapor;

- cheaper heat production;

- increased reliability;

- fuel economy by 15-20%.
