The lack of technical solutions for the single-stage preparation of hot water are excessive consumption of resources, energy and operating costs caused by seasonal fluctuation of temperature of the cold water heat on "paratope" buildings with a cutoff temperature graph.

The aim of the invention is to increase efficiency by reducing the capacity of the tank, reducing the consumption of resources, energy and operating costs.

This is achieved by the fact that the heater for the heating system, dopolnitelnih and attached to the pipe entering the household water supply to the heated line to the inlet of the heat exchanger of the second stage, and another (with valve and check valve to the outlet of the tank and piping hot water, and condenser of the first heat pump is installed on the line of the heated water leaving the heat exchanger of the first stage, the evaporator and the condenser of the second heat pump, placed respectively on the pipelines of hot and cold water, the condenser of the second heat pump is installed on the hot water pipes between the heat exchanger of the second stage and the place of connection of the bypass pipe to the hot water pipes, pipe heated line after the heat exchanger of the first stage has a water tap, the input of which is connected with reverse heat, and the exit - entrance of the heat exchanger of the second stage.

Summary of the invention in the following. Cold water, heated by the warmth of the back of the heat, knowledgeable consumers, resulting in lower costs of hot water, coolant, fuel supply sources, gas pipelines, electricity grids, to reduce consumption of metal and other resources in engineering systems, to the exclusion of condensate on the surface of the cooling water pipes and surface corrosion to uvelichenie condenser of the second heat pump reduces the capacity of the tank.

In Fig.1 is a diagram of the boiler; Fig.2 - same as option.

Heat the feed item contains 1 and return pipes, heat exchangers, respectively, the first 3 and second 4-speed, piping hot 5, circulation 6 cold 7 water heat pumps 8 with the evaporator 9 and the capacitor 10 and 11 with the evaporator 12 and the condenser 13, the control valve 14 with the sensor 15 temperature, check valves 16-19, the pipe 20 is heated line after the heat exchanger of the first stage, valves 21-24, tank battery 25, pipe 26 entering household water supply, bypass pipelines 27 and 28, pump 29, the mixer 30, pipe 31, connecting the input to the mixer, and the reverse heat.

The scheme of the boiler (Fig.2) when the temperature of the cold water automatic thermostat contains a bypass 32 pipe with non-return valve 33 of the tank and the control valve 34 to the sensor 35 temperature on the cold water line 7.

Heater works when the heat pump 8 and 11. In this case, valve 23 in the heating season is closed and valves 21 and 22 are open only on the range "cutting" of the temperature graph. When the total water St is depravada with temperature tx is supplied to the heat exchanger 3, heats up in its warmth reverse 2 of the heat that passes the condenser 10 of the heat pump 8, where doreverse to a temperature tx1.

From the condenser 10 water enters the mixer 30, and into the evaporator 12 of the heat pump 11 that is installed on the cold water line 7. From the evaporator 12 cold water with a temperature tx11> tpon line 7 is supplied to consumers tp- temperature of dew point on the surface of the pipeline 7). With minimal water points from the condenser 10 cold water was also fed to the charging tank 25. In the mixer 30, the water coming from the condenser 10, is mixed with water from the reverse of a heat pipe 2 is supplied through the conduit 31, and the pipe 20 enters the preheating in the heat exchanger 4 of the second stage, which is fed to the condenser 13 of the heat pump 11, degraves there until the estimated temperature tgand the pipeline 5 is motorspor, and the crosspiece 28 - charging tank 25 when "logging" temperature graph.

The heat pump 8 and 11 makes it possible to reduce the surface heating heat exchanger and the tank capacity of the battery. Maintaining the water temperature in drobopro altnoy water and condensate on the surface of the piping 7 which eliminates the need for thermal insulation), 25-35% reduction in the cost of hot water, heat and fluid delivery conduits, reduce costs, gas pipelines and electricity grids (which leads to an increase in throughput of engineering networks), the consumption of metal and other resources, as well as operational costs of power supply systems.

On the range "cutting" temperature chart open valves 21 and 22 to bypass pipelines 27 and 28, which serve to bypass the heated water to regulate the temperature of the coolant at the outlet of the heat exchanger 4 on schedule quality regulation and because of this exception, loss of warmth on paratope". When this control valve 14 by the pulse from the sensor 15 temperature regulates the flow of water from pipe 26 to the inlet of the heat exchanger 4. The degree of opening of the valve 14 increases with increasing outdoor temperature. At this range, charging the battery 25 through two rings: the pump 29 to the heat exchanger 3 to the capacitor 10 of the heat pump 8 - tank battery 25 and the pump 29 by - pass pipe 27 to the heat exchanger 4 by - pass pipe 28 - tank battery 25. The higher the outdoor temperature, the higher the water consumption is proprovide 2, where it is heated in the network heaters heat extraction steam in the peak heater (or peak boiler) and feeding the heat pipe 1 is fed to thermal areas of the district energy supply. In addition utilized waste heat cooling condensers, steam turbines, resulting in fuel savings, increased electricity generation at CHPP, to cost reduction in installation of cooking heat and cooling of the turbine condensers, as well as to the reduction of environmental pollution by waste combustion.

When the temperature of the cold water in the pipe 7 automatic regulating valve heater works similarly considered the basic scheme. However, (see Fig.2) cold water from pipe 26 input comes in line 7 on Obvodny pipe 32 with a check valve 33, and the amount of water coming from the condenser 10 in the pipe 7, is regulated by the regulating valve 34 sensor 35 cold water temperature.

At mixing chamber outlet, this two-phase flow is decelerated for forming shock wave and converting the flow into liquid flow after shock wave. Then, flow is divided and one part is directed to heat exchanger of vortex tube where it is heated and directed for replenishment of electric steam generator. Other part is directed to nozzle apparatus where it is accelerated to supersonic velocity for forming two-phase flow, after which it is decelerated for converting it into liquid flow saturated with micro-bubble component. Nozzle apparatus outlet is connected with swirler inlet where vortex flow is formed; from swirler, flow is directed to vortex tube where heat is released and flow is divided into hot and cold components. From vortex tube, flow is directed to heat exchanger for transfer of heat to second loop; cooled liquid flow is directed to ejector inlet.
