How to exhaust the wall-mounted furnace radiator
As winter approaches, the frequency of use of wall-hung boilers and radiators gradually increases. However, many users encounter the problem that the radiator is not hot or makes too much noise during use. This is often due to the accumulation of air inside the radiator. This article will introduce in detail the steps and precautions for exhausting the wall-mounted boiler radiator to help you easily solve this problem.
1. Why is exhaust needed?
The accumulated air inside the radiator will affect the circulation of hot water, causing the radiator to be partially or overall not hot. In addition, the presence of air will generate noise and affect living comfort. Therefore, regular exhausting is an important step to ensure efficient operation of the radiator.
2. Preparations before exhausting
