In winter, when the temperature of the hot water in the solar collector is higher than the temperature of the heating return water, the hot water in the solar collector can exchange heat with the closed loop return water for heating through the heat exchanger, and the return water and the solar collector The hot water in the heater is fully exchanged in the heat exchanger. After the temperature rises, it is heated to the heating temperature by the gas wall-hung boiler, and the water pump provides power for circulation. The heat of the circulating hot water is radiated into the room by using the indoor cooling device. In winter, when the temperature of the hot water in the solar collector is higher than 45°C, it can be used for bathroom equipment. If the temperature is lower than 45°C, it can be heated by the heat supply and return water in the gas wall-hung boiler through the heat exchanger. For bathroom use.
