[0002] Heating is one of the earliest building environment control technologies developed by humankind. Since humans learned to use fire, they have invented heating methods such as heated brick beds, stoves, heated walls, and heated floors to resist the threat of cold to survival. These are the earliest heating equipment and systems, some of which are still in use today. Today, heating equipment and systems have made great strides in terms of human comfort and hygiene, the aesthetics and ingenuity of the equipment, the automatic control of the system and equipment, the diversification of system forms, and the efficient use of energy.

[0003] my country has a vast territory and abundant natural resources. High-altitude areas have high solar radiation and long sunshine hours. However, heating and domestic hot water in high-altitude and low-latitude areas mainly rely on burning coal and firewood, which wastes natural resources and pollutes the environment. Therefore, those skilled in the art provide a multi-energy coupled heating system to solve the problems mentioned in the background art. Utility Model Content
