Maintenance of radiator:
The radiator has been idle until the next heating season. Therefore, it is necessary to clean and protect the radiator before heating. It is also important to maintain the radiator correctly.
Before the arrival of the new heating season, check the exhaust valve, plug and pipe fittings connected with the radiator, and tighten the threaded joint if it is loose (affected by thermal expansion and contraction) to avoid water leakage after heating. In addition, please use a soft towel or brush when cleaning the radiator surface. Do not use any organic solution. You can use daily detergents, such as detergent and weak alkaline soapy water.
Understand the material of radiator and the correct maintenance method of radiator. Different materials of heat sinks have different maintenance methods. For example, steel heat sinks generally need full water maintenance, while aluminum ones do not.
Therefore, before we are ready to start the radiator heating, how to do a good job of cleaning is very important and must not be sloppy. After all, if you want to spend the whole winter comfortably, the radiator is a great hero.
