The pressure release valve 100 may be configured to automatically release pressure when the pressure in the water storage tank 40 reaches a set value, thereby preventing explosion of the water storage tank 40 due to excessive internal pressure. Also, the relief valve 100 may be provided in conjunction with the pumping unit P, the electric auxiliary heating unit 50 to ensure that the pumping unit P and the electric auxiliary heating unit 50 are closed when the relief valve 100 is relieved.

The following describes different working conditions of the domestic hot water supply system of the present application with reference to the accompanying drawings.

The domestic hot water supply system has the following working conditions:

heat storage working condition: when the gas range is started, the pumping unit P is started at the same time, water in the water storage tank 40 flows into the heat exchange cavity 111 through the outlet via the water inlet pipe 20, the water in the heat exchange cavity 111 is heated by heat exchange with the annular inner wall and the fins 12, and the heated hot water returns to the water storage tank 40 through the inlet via the water outlet pipe 30, so that the heat storage cycle is completed. In this condition, hot water may be taken through the hot water supply line 70 at the same time.

Normal use of domestic hot water conditions: the hot water of the hot water supply line 70 and the cold water of the water replenishment line 80 are mixed by the water mixing valve 90, and then the hot water can be taken through the tap 110. When the pressure decreases below the water pressure in the water replenishment line 80 due to a decrease in the amount of water in the water storage tank 40 caused by taking hot water, the water replenishment line 80 automatically replenishes the water storage tank 40 through the water replenishment port.

Excess use of domestic hot water conditions: the hot water of the hot water supply line 70 and the cold water of the water replenishment line 80 are mixed by the water mixing valve 90, and then the hot water can be taken through the tap 110. Under this condition, the monitoring unit 60 monitors that the water temperature in the water storage tank 40 is reduced (the water supplementing amount is larger than the water storage amount of the heat storage cycle, the temperature is reduced) or the water outlet temperature requirement cannot be met due to the fact that the water consumption cannot be met, and the electric auxiliary heating unit 50 is started to assist in heating the water in the water storage tank 40 to the required temperature.

Water discharge working condition: the pressure in the water storage tank 40 is too high to reach the set value of the pressure relief valve 100, the pressure relief valve 100 is opened to automatically relieve pressure, and the pumping unit P and the electric auxiliary heating unit 50 are closed.
