Through the above design, the water temperature of the bathroom water outlet can be adjusted, and the flow of cold water entering the second installation cavity 121 can be accurately controlled. The warm water after heat exchange with the plate heat exchanger is mixed through the water mixing valve 5 to accurately control the water temperature of the outlet, achieve the constant temperature effect, and quickly and accurately adjust the wall-hanging stove. The energy consumption of the wall-hanging stove is effectively reduced, and the service life of the wall-hanging stove is improved.

[0030] When the water in the floor heating is used, the circulating hot water heated in the wall-hanging stove flows into the first installation cavity 112 from the hot water inlet 113, and then flows into the floor heating pipeline from the hot water floor heating interface 111.
