What should I do if the air pressure of wall-hung boiler is high?

If the wind pressure of the wall-hung boiler is too high, it may cause problems such as insufficient combustion, too high furnace temperature, too slow pressure release, and even the danger of explosion. Therefore, if the air pressure of the wall-hung boiler is too high, measures should be taken as soon as possible to solve it.

First of all, it is necessary to confirm whether the air pressure of the wall-hung boiler is really too high, which can be detected by the pressure gauge of the wall-hung boiler. If the test results show that the air pressure is too high, it is necessary to adjust the air pressure of the wall-hung boiler.

The adjustment method of wind pressure of wall-hung boiler varies with the model and brand of wall-hung boiler. Generally speaking, it can be operated by the following steps:

1. Turn off the power and water supply of the wall-hung boiler, and wait for a few minutes for the wall-hung boiler to cool completely.

2. Find the air pressure regulating valve of the wall-hung boiler, which is usually placed at the lower part or side of the wall-hung boiler.

3. Test the wall-hung boiler with barometer, and pay attention to whether the pipeline leaks. If the detected air pressure is out of the range given by the manufacturer, it needs to be adjusted.

4. Set the air pressure regulating valve to the correct air pressure value according to the instruction manual of the wall-hung boiler. Generally, the air pressure value should be between 1.2- 1.5 bar.

5. After adjustment, test again with barometer to ensure that the air pressure has been adjusted to the required range.

Pay special attention to the maintenance or troubleshooting of the wall-hung boiler. If you are not familiar with the operation of the wall-hung boiler or have any questions, please contact professional and technical personnel in time.
