As shown in fig. 11, the wall-hanging stove is in a zero cold water circulation state, the temperature detection unit detects the temperature of the domestic water in the domestic water channel 41 in real time, when the temperature of the domestic water is lower than a set temperature, the main heat exchanger 2 is controlled to operate, the reversing valve 6 is controlled to communicate the working inlet 61 with the first working outlet 62, and the clutch 522 is controlled to be in a connection state, so that the heating water impeller device 53 and the domestic water impeller device 54 operate simultaneously; the heating water circulates in a circulation pipeline formed by the main heat exchanger 2 and the plate heat exchanger 4 under the action of the heating water impeller device 53; meanwhile, the low-temperature domestic water in the water return pipe enters the domestic water impeller cavity 516 through the domestic water return end 13 and the second water inlet interface 513, flows out from the second water outlet interface 514 under the action of the domestic water impeller device 54, then enters the plate heat exchanger 4 for heat exchange and temperature rise to form high-temperature domestic water, and the high-temperature domestic water is discharged through the domestic water outlet end 12 and flows to the hot water outlet pipe.

The set temperature may be a temperature set by a user, or may be a hot water temperature suitable for direct use determined by experiment.
