Why has the radiator been deflated, drained and cleaned, and the radiator has been replaced, but it is still not hot?

The main problem of heating is the gas accumulation in the pipeline, which leads to poor water circulation. When residents drain water from the radiator, in fact, the radiator releases gas, and the amount of water released is very small. Some residents don't understand that putting a large basin of water not only wastes water, but also makes the hot water in the heating pipe not stored enough, resulting in the heating not reaching the appropriate temperature.

There are many reasons why the radiator is not hot, so you can't drain water without authorization. If the water is drained without authorization, it will cause a certain link in the system to lose water, resulting in the pressure change of the heating system, and a large amount of hot water will be lost in the pipe network, which will lead to the radiator becoming less and less hot. In addition, the radiator has high water temperature and high pressure, and also contains chemicals harmful to human body. It is best not to release the water in the radiator at will.

The specific deflation method of heating is as follows: there is a manual exhaust valve on each radiator. Users can gently twist the manual exhaust valve, stop twisting the exhaust valve immediately when they hear the exhaust sound, and gently tighten the exhaust valve if there is stable water flowing out. After exhausting, if the radiator is still not hot, please ask a professional to find out the reason and help solve the problem. Never drain water blindly.
