Working principle of heating:

Heating can be divided into water heating and air heating. Usually radiator refers to water heating, that is, circulating water is heated by wall-hung boiler or boiler, and then linked to radiator through pipeline. Finally, the appropriate temperature is output through the radiator to form the indoor temperature difference, and finally, the whole indoor temperature is evenly increased through thermal circulation.

Warm air is hot air. As soon as the cold air comes in, it is heated into hot air by the radiator. Hot air rises and forms convection with indoor cold air. Cold air circulates near the heater and is heated into hot air. Hot air circulates in the house and the room is warm.
