What are the causes and solutions of local overheating of radiators?

Indoor heating is basically divided into loops, and each room is a loop. Of course, such a situation will not appear in the traditional series heating mode. For example, the radiator installed in our bedroom is partially blocked, which will lead to poor circulation. At this time, the hot water does not circulate quickly in the radiator, but directly flows back along the return pipe, which will lead to the radiator's heat dissipation not meeting the requirements.

In view of this situation, we must first find this single-loop valve in the bedroom and find the control valve. At this point, turn down other loop valves and open the bedroom loop valve. Next, you can remove a part of the whole circuit, such as radiator plug, for drainage or cleaning.

The second is caused by local gas accumulation.

For indoor heating, it is easy to cause no heat because there is gas in the pipeline or radiator, which seriously affects the normal circulation of hot water.

The method of exhausting the radiator is very simple. We only need to open the exhaust valve located on the upper left or upper right side of the radiator and manually exhaust ourselves. At this time, you must use the water receiving tool to receive water, and then exhaust all the gas inside. The standard of qualified exhaust is: all clean hot water is exhausted without any gas, so the exhaust is completed.

Third, other reasons.

Others, such as the aging of heating facilities and the limited service life of pipe network radiators, will cause internal corrosion, scaling and serious blockage due to users' failure to maintain on time, which will affect the heat dissipation effect.

Some users install or disassemble radiators privately, which is easy to cause uneven heating due to irregular installation, unreasonable position and many bends.
