What is the reason why the old radiator is not hot?

Many radiators installed in old communities are old-fashioned radiators. If the old radiator is used for a long time, it will inevitably lead to overheating and water leakage, which will affect the normal use of the owners. What is the reason why the old radiator is not hot? Let's take a look with Bian Xiao.

What is the reason why the old radiator is not hot?

There are many reasons why the old radiator is not hot, and the treatment methods are different. Therefore, when it is found that the old radiator is not hot, first find out the reason, and then take corresponding measures to solve the problem, as shown in the following figure:

1, service life expires.

Old-fashioned radiators have a service life of up to 8 years. If the owner doesn't do a good job of maintaining the old radiator in his daily life, the inside of the old radiator is prone to corrosion or scaling, so the old radiator will naturally not be hot. At this time, you should contact professionals to clean and maintain the old radiator, or directly replace the new radiator.

2. The filter screen is blocked

The water inlet pipe of the old radiator is generally equipped with a filter screen to filter the dirt in the water. If the old radiator is seriously corroded or there is dirt in the water, the filter screen will be blocked, which will lead to poor heating cycle of the old radiator, so the old radiator will naturally not be hot. At this time, you should contact professional maintenance personnel to help clear the heating pipe and clean the filter, or directly contact the heating company to help replace the new heating pipe.

There is air in the pipe.

When water flows into the heating system, some air usually accumulates in the water. If there is air accumulation in the heating system of the old radiator, it will naturally lead to the phenomenon that the old radiator is not hot. At this time, the exhaust valve of the old radiator should be opened to let the air in the heating system exhaust.

The above is Bian Xiao's introduction about why the old radiator is not hot, hoping to help you solve the problem that the old radiator is not hot. When it is found that the old radiator is not hot, the reason should be found first, and then corresponding measures should be taken to deal with it.
