A system for water heat supply has at least one solar heat collector, boiler with heat exchanger placed in its cavity, at that solar heat collector, heat exchanger and pipelines that connect those form a closed system filled with heat carrier, boiler through inlet branch pipe is connected to heat supply system, and through discharge branch pipe – to consumer of heated water. The system additionally includes a heat pump, two high-speed heat exchangers as vessels, in the first heat exchanger evaporator is placed, and in the second one – condenser of heat pump. The high-speed heat exchangers have inlet and outlet branch pipes, inlet pipes are connected with pipelines to discharge branch pipe of solar heat connector, and discharge pipes of quick heat exchangers – to inlet pipe of solar heat collector. Between the discharge pipe of the first high-speed heat exchanger and inlet pipe of solar heat collector a check valve and circulation pump are installed, and between the discharge branch pipe of solar heat collector and inlet branch pipe of the second high speed heat exchanger three-way cock is installed, this is connected through pipeline, check valve and circulation pump to inlet pipe of heat exchanger placed in the boiler cavity. |
