Why and how the radiator exhausts?

Water usually contains a certain amount of air. This is because there is still gas in the pipeline, which cannot be completely emptied when exhausting. After circulating operation, the gas in the pipeline stays in the radiator. During the operation of heating system, the solubility of air will decrease with the increase of temperature, and air will gradually separate from water.

Because water is constantly replenished, gas is often produced. If it cannot be discharged in time, it will have many adverse consequences: oxygen will be separated from hot water.

During the operation of radiator system, there will be gas in the pipeline, which will be stored at the highest point of the system. When these gases accumulate to a certain extent, there will be a phenomenon of "gas blockage", which will hinder the activity of water in the system pipeline, and the heat conduction radiator will be not hot or unevenly heated, so it is necessary to deflate.

Precautionary measures for radiator exhaust;

When the heating is half hot and half not hot, and there is water noise in the heating, it is because the air in the heating is not completely exhausted, and it is necessary to open the air valve to deflate until water comes out. Sometimes it needs to be deflated many times, and one or two times is not enough to clean up, so it can be deflated once every once in a while until it is used up.
