Through the wall-hanging stove that this embodiment provided, can realize three kinds of heating modes:

first, individual heating mode: as shown in fig. 3, the arrows in fig. 3 give the flow direction of the water flow:

in the single heating mode, only heating equipment such as floor heating and the like is heated. Firstly, the burner is controlled to be started, and the first heating unit and the second heating unit are subjected to temperature rise operation. The low-temperature water in the heating equipment firstly enters the fourth pipe through the heating water return port, the fourth pipe 11 is communicated with the first water inlet 101 of the first heating unit, and the water is firstly heated in the first heating unit. After the primary heating is finished, the water flows out through the first water outlet 102 and enters the first three-way valve 7, then flows into the second water inlet 201 of the second heating unit 2, and is heated for the second time, after the secondary heating is finished, the water flows out through the second water outlet 202 and enters the second pipe 8, and at the moment, the second three-way valve 9 is controlled to be directly connected with the heating water outlet 4, so that the water heated twice flows into the heating equipment.

Second, single life hot water mode: as shown in fig. 4, the arrows in fig. 4 give the flow direction of the water flow:

in the single life hot water mode, water does not enter the heating device. The water pump 16 is started, the circulating water flows out from the heat exchanger 5 and flows into the third three-way valve 13, then enters the fourth pipe 11 according to the direction shown by the arrow in the figure, the water in the fourth pipe 11 firstly flows into the first heating unit for preliminary temperature rise, then flows out from the first water outlet 102 and enters the first three-way valve 7, the water flowing out from the first three-way valve 7 flows into the second water inlet 201 of the second heating unit 2 again, temperature rise is carried out again in the second heating unit 2, the water after temperature rise again flows out through the second water outlet 202 and enters the second pipe 8, the water flow flows into the second three-way valve 9, then flows into the third pipe 10 under the diversion of the second three-way valve 9, and flows back into the heat exchanger 5 through the third pipe 10.

The heat exchanger 5 is simultaneously connected with a domestic hot water inlet 501 and a domestic hot water outlet 502, and water heated by the first heating unit and the second heating unit simultaneously exchanges heat with domestic hot water in the heat exchanger 5, so that the temperature of the domestic hot water is ensured.

And thirdly, a heating and domestic hot water mode is simultaneously realized. As shown in fig. 2, the arrows in fig. 4 give the direction of flow of the water flow:

the water pump 16 is started, and the heating water inside the heating apparatus flows into the fourth pipe 11 through the heating return water port 3, and then enters the first heating unit through the first water inlet 101 to be heated. The water heated by the first heating unit 1 flows in through the first water outlet 102, then flows into the first three-way valve 7, and by controlling the first three-way valve 7, the water flowing out through the first three-way valve 7 flows into the third pipe 10, and the water flowing out through the third pipe 10 flows into the heat exchanger 5 for heat exchange. The heat exchanger 5 is connected with a domestic hot water inlet 501 and a domestic hot water outlet 502, and hot water flowing out through the first heating unit heats water flowing into the heat exchanger 5 through the domestic hot water inlet 501, so that domestic hot water is prepared.

Meanwhile, the water flowing out through the heat exchanger 5 flows into the third three-way valve 13, then flows into the second heating unit 2 through the second water inlet 201 to be reheated, the reheated water flows out through the second water outlet 202 and flows into the second pipe 8, and after the water flow flows into the second three-way valve 9, the third three-way valve 9 is controlled to enable the water flow to directly flow into the heating water outlet, so that the heating water is prepared.

In this embodiment, the preparation of the hot water for domestic use and the heating water can be simultaneously realized by controlling the first three-way valve, the second three-way valve, the third three-way valve, the first heating unit and the second heating unit.

Specifically, first three-way valve, second three-way valve, third three-way valve are the solenoid valve, can realize the control to the different flow directions of three-way valve through simple control logic, carry out too much restriction to the three-way valve in this embodiment.
