One, do radiators require cleaning?

Yes. As a commonly used heating device, radiators are prone to scale buildup during the heating season. Heating companies typically add a large amount of anti-scaling chemicals to the heating system to prevent this. Although this measure is effective to some extent, scale buildup still occurs easily due to poor water quality or other reasons after the radiators are used.

If excessive scale buildup occurs in the radiator, it not only affects the user's heating performance but also leads to energy waste. Therefore, regular cleaning of radiators is essential.

Two. How often should radiators be cleaned?


During use, heating users should properly maintain and care for the radiators. If scale buildup occurs inside the radiators, they should be cleaned periodically, typically every 3-5 years.

III. How to clean radiator

1. First, close the return valve of the radiator.

Before cleaning, to ensure safety, it is essential to turn off all return valves and then use a wrench to gently loosen the plug on one side of the radiator.

2. Secondly, clean the radiators.

Open a temperature control valve, flush it to remove any debris or sediment until the water flowing through the radiator is clear. once the water is clear, close the temperature control valve. Repeat this process for all radiators. After cleaning, open the inlet valve and bleed the air from the system.

3. Clean the pipes

After the radiators stop operating, it is important to promptly clean and maintain the filters and clean the system pipelines as needed to prevent the accumulation of debris and blockages, which can make it difficult to clean later.

Please note: Different types of radiators require different cleaning methods. It is best to have a professional technician come to your home to clean the radiators, as this will help to avoid any damage during the cleaning process.
