Volkswagen Yu Ling 1.8t heating pipes don't circulate. Why?

1, there is a problem that heating water does not circulate. It may be that the radiator is installed in the pipeline for too long, which will increase the circulation time and slow down the circulation speed, resulting in poor circulation and the radiator is not hot.

2. Another reason is that because of central heating, there will be a problem of insufficient hot water pressure, which will lead to poor communication.

3. Some people don't open all the water inlet pipes or return pipe when heating with radiators. At this time, the water flow will be relatively small, thus reducing the speed of water circulation.

4. When installing radiators, you should also pay attention to the fact that the more radiators are installed, the better. If there are more radiators than the usable area, the water circulation will slow down, which will cause the scale inside to condense and the heating effect will be poor.

There is also a situation that the radiator needs to be used every year, which will inevitably lead to the problem of blockage, especially if there is air or other debris blocking it, which will lead to the lack of circulation of the heating.
