Proper storage of heat in the PB 3 is a matter of comfort in using the system. When the RB 3 is installed on the ceiling, due to the provision of a standardized pump head, the uro and consumption of hot and cold water increases. 2 Il.

The invention relates to hot water supply systems of residential one-story houses with their heat supply from water heaters embedded in heat generators on solid, liquid or gaseous fuels, and can be used for hot water supply of industrial buildings with decentralized heat supply.

The purpose of the invention is more complete satisfaction in the hot water of consumers.

FIG. 1 is a schematic diagram of an autonomous system for supplying water to a residential house; Fig.2 - expansion tank.

The hot water supply system contains a heat generator 1 with a built-in water heater, a hot water storage tank 2 made in the form of a vertical cylindrical column, an expansion tank 3 including a tank 4 with a float valve 5 mounted on a tubular column 6, a supply pipeline 7 mountains whose water from the heat generator 1 is connected to the storage tank 2 at a height of 1 / 4-1 / 5 of the vertical dimensions of the latter, the return water pipeline 8 connected to the storage tank 2 in its lower zone, to which are also connected ribbed column 6 the expansion tank 3, the feed line 9, a mixer 10 in the bathroom taps and washing sinks 11 via conduit 12. To the upper zone of the tank, the battery 2 connected tubular column. 6 by means of the circulation pipe 13, and the mixer 10 and the taps of the sinks 11 - with the encouragement of the pipeline 14. The cold water supply pipe 15 is connected to the float valve 5 of the expansion tank 3, and the inlet pipe 15 is turned into 0

the tubular column 6 is located through the bottom of the tank 3. Inside the tank 4, an overflow pipe 16 is installed, which has a drain into one of the sanitary facilities, for example, the sink 11.

The expansion tank 3 is installed on the ceiling of a residential building on the supporting structure 17 adjacent to the chimney .18 and enclosed in a casing 19 filled with insulating material. A faucet 20 is installed on the cold water pipe 15.

Autonomous system of hot water works as follows.

When the washing taps 11 and the mixer 10 and the open tap 20 are closed, cold water supply pipe 15 supplies water to the tank 4 of the expansion tank 3 through the float valve 5. Cold water fills the storage tank 2 and the tank 4. When the maximum level is reached The last float closes the valve 5. Then the heat generator 1 is ignited and the water which heats up under the action of natural circulation is moved through the supply and return pipes 7 and 8 between the heater of the heat generator 1 and the tank A pump 2. To lower the temperature of the water in the return pipe 8, it is recommended to connect the hot water supply pipe 7 to the storage tank 2 at a level of 1 / 4-1 / 5 of its height. Hot water rises into the upper zone of the storage tank 2.

Upon reaching the required temperature, the water opens the cold and hot water taps of the mixer 10 and during regulation selects the required water temperature after the mixer 10. At the same time, the water level in the tank 4 decreases and the float of the valve 5 lowers with it, opening the cold water in the tank 4 by pipeline

15. Through the discharge pipeline 9 cold water enters the storage tank 2, and from there through pipeline 8, into the water heater built into the heat generator 1. The water in the water heater of the heat generator 1 is heated through conduit 7 again to the storage tank 2, collected in its upper zone and via conduit 14 to the mixer 10 and to the wash basins 11.

During the period when the heat generator 1 does not work, the natural circulation of water between the storage tank 2 and the expansion tank 3 through the pressure and circulation pipes 9 and 13, respectively, is established.

Non-freezing of water in the expansion tank 3 during periods between start-ups of the heat generator 1 is also prevented by heat accumulated by brick masonry of the chimney 18 during the operation of the heat generator 1, by the circulation of water between the expansion tank 3 and the storage tank 2 and thermal insulation filling the casing nineteen.

Thus, by introducing into the autonomous system of hot water supply of a residential house additional circulating 13 and pressure 9 pipelines connecting the storage battery 2 to the expansion tank 3, and placing the input end of the water pipeline 15 in the cavity of column 6 of the expansion tank 3, Additional heat storage is provided in the expansion tank 3,

which contributes to a more complete satisfaction in the hot water of consumers in a residential home.

In addition, when installing the expansion tank 3 on the ceiling of a residential building close to the chimney 18, the level of comfort of the system is increased by providing normalized head and hot and cold water flow before the bath mixer 10 and other sanitary appliances.
