[0002] There are various heating equipments in the market, and the heating methods are varied. At present, my country's heating industry presents three obvious development trends, namely, comfort, green and low carbon. Central heating has obvious advantages in meeting the appropriate indoor temperature environment, but it is difficult to meet the comfort and personalized needs of residents. With the continuous rise of household heating methods in the south, the high-quality consumption demand for heating with comfort, personalization and artistic requirements will continue to increase. Because water heating is very comfortable, not dry and noiseless, it is generally welcomed by people of all ethnic groups in the world. However, traditional central heating and household distributed self-heating generally must be installed before house decoration, otherwise, only open pipes can be installed, which is not beautiful and also destroys the decoration of the original house. At the same time, since household self-heating must include equipment that generates heat sources such as wall-mounted boilers or air-energy water heaters, water distributors, multiple sets of valves, complex pipes, radiators and professional construction and installation workers, the one-time purchase cost is relatively high. Like central heating, since the pipe installation is all pre-buried in hidden walls or ground, traditional water heating has leakage risks and is difficult to replace and repair.
