The heat preservation measure of large volume of the heat storage water tank is particularly important, so that the heat storage water tank is provided with the heat storage water tank outer heat preservation 36, and the heat storage water tank heating principle is adopted in the cross-season: when heating, the heating circulating water pump 22 is started, the heating low-temperature backwater enters the first heat exchanger 33 of the heat storage tank heating heat exchanger through the heat exchanger heating water inlet pipe inside the heat storage tank heating heat exchanger water inlet pipe 14, then passes through the second heat exchanger and the third heat exchanger, and is heated into heating high-temperature water, and the heating low-temperature backwater flows out from the heating water outlet pipe 13 of the heat storage tank heating heat exchanger and is supplied to the tail end to heat the building. When the heating system heating water supply temperature sensor detects that the heating water supply is too high, the system starts the heating water supply temperature regulating electromagnetic valve 15, and at the moment, the heating low-temperature water part directly enters the heating water supply pipe through the heating water supply temperature regulating electromagnetic valve 15, so that the water quantity entering the heat storage tank heating heat exchanger is reduced. The low-temperature water directly entering the heating water supply pipe by the heating water supply temperature-adjusting solenoid valve 15 is mixed with the high-temperature water coming out of the heat storage water tank, thereby reducing the temperature of the system water supply pipe. If the heating water supply temperature is higher than the heating set temperature value, the heating water supply temperature regulating electromagnetic valve 2 and the heating water supply temperature regulating electromagnetic valve 3 are continuously opened until the system heating water supply temperature is reduced to the set heating temperature. The pipeline provided with the heating water supply temperature regulating electromagnetic valve can be selected according to 1/4-1/3 of the pipe diameter of the heating water supply return pipe so as to realize effective control of heating temperature. After a softened water level meter of a softened water tank 12 arranged in a cross-season heat storage water tank and a water replenishing system of a heating system detects that the softened water level is lower than a set value, a tap water inlet electromagnetic valve 10 is opened, tap water enters the softened water tank 12 after passing through a soft water changing device 11, after a period of time, the softened water tank level rises to a set high limit water level, the soft water changing device 11 is closed, and the water replenishing system completes softened water storage. After the heat storage tank liquid level meter 32 arranged on the heat storage tank 31 crossing seasons detects that the liquid level of the heat storage tank is lower than a set value, a water supplementing electromagnetic valve of the heat storage tank is started, and a heating system and a water supplementing pump 17 of the heat storage tank are started at the same time, so that the water supplementing function of the heat storage tank is realized. After the water level of the heat storage water tank rises to the set high limit water level after a period of time, closing the water supplementing solenoid valve of the heat storage water tank, the heating system and the water supplementing pump 17 of the heat storage water tank, and completing water supplementing of the heat storage water tank. The heating system backwater is provided with a heating system constant pressure tank 20, and plays a role in stabilizing the system pressure. Meanwhile, a heating system water return pressure sensor 21 is installed. The system controls the opening and closing of the heating system, the heat storage water tank water supplementing pump 17 and the heating system water supplementing valve according to the set pressure and the value detected by the pressure sensor, and realizes the constant pressure of the heating system.
