The outer sides of the circulating insulation water tank 2 and the heat storage insulation water tank 3 are both provided with insulation layers, which are used to keep the circulating insulation water tank 2 and the heat storage insulation water tank 3 warm.After the control center controls the first electric control switch 23 to be turned on, the air energy heat pump 1 starts to heat the water. At this time, the second electric control switch 24 is turned on, and the heating circulation pump 10 starts to work to increase the water temperature in the circulating insulation water tank 2. Then the heat storage tank return water solenoid valve 5, the circulation tank return water solenoid valve 9 and the circulation tank water supply solenoid valve 8 are turned on. At this time, the circulating insulation water tank 2 and the heat storage insulation water tank 3 are in a connected state, so that more heat can be stored in the heat storage insulation water tank 3. After the water temperature of the heat storage insulation water tank 3 rises to a certain level, the third electric control switch 25 is controlled to be turned on, and the heating circulation The ring pump 6 starts to work, and then provides heat energy to the room through the heater 4.
