Radiators are often deflated regularly to keep the system functioning properly while they are in use. The purpose of venting is to remove air from the system to ensure that the radiator can supply heat normally and avoid problems such as uneven heating or noisy air valves.
Here are some guidelines on venting radiators:
1.Deflation at high points: Air tends to collect at high points in the system in heating systems, such as radiators or water tanks in the upper part. Regular deflation can help to remove this air so that hot water can flow fully to each radiator, improving the heating effect.
2.Deflation tool: Deflation can usually be done with a dedicated deflation valve. These bleed valves are usually located on the body of the radiator or at a point with a similar function. Using a wrench or special tool, hit the air release valve counterclockwise until you hear the sound of the gas being discharged. Take care to ensure that there is a container to receive the discharged water or air when deflating.
3.Regular inspection: Depending on the situation, it is recommended to carry out a degassing after the end of each heating season and before the start of the heating season to ensure the proper functioning of the system. In addition, if you notice unusual noises in your heating system, leaking valves, or uneven heat supply, you should also deflate immediately.
It is important to note that there may be a risk of hot water splashing or scalding during the deflation process. Always make sure the heating system is cooled down and operate with caution before venting. If you are unfamiliar with or unsure about the deflation operation, it is recommended to seek the help of a professional heating engineer or radiator repairer to ensure safe and correct operation.
