What should I pay attention to when the heating stops?

If it is collective heating, you'd better turn off the inlet valve and the return valve when you stop heating, because there are antiseptic drugs in this heating water, which can prevent the radiator from rusting.

If these valves are not closed, there will be moist gas in the radiator, which will gradually corrode the radiator from the inside and affect its life. If there is original heated water, it can prevent rust.

Extended data:

Radiator is a kind of heating equipment which mainly focuses on heating. It is mainly used in the northern areas where winter is cold, and has the function of keeping warm. Cast iron radiators were mostly used in the past, but now more materials have been developed.

Cast iron radiators have gradually withdrawn from the market stage, and new radiators such as steel radiators, copper-aluminum composite radiators and aluminum radiators are superior to cast iron radiators in materials and manufacturing processes, becoming the most mainstream radiators in the market.

1 [central heating] The hot water or steam discharged from the boiler enters the radiator (commonly known as radiator) in the building through pipes, and the room temperature is raised after heat dissipation. Hot water or steam in the pipeline is called heating. Generally, the above equipment is also called heating.

2. Heating, also known as radiator, radiator, radiator, etc. , which is the cooling terminal of the heating system. The main materials are cast iron, steel, aluminum and copper-aluminum composite materials. , and together with hot water (steam) boilers, heating pipes, valves, measuring instruments, etc. , forming a building (or a single household) heating system.

3. Warm gas.
