What should I do if the water pressure of the wall-hung boiler is too high?
Wall-mounted boilers are important equipment for heating in winter for many families, but during use, you may encounter problems with excessive water pressure. Excessive water pressure will not only affect the normal operation of the wall-hung boiler, but may also cause safety hazards. This article will give you a detailed analysis of the causes and solutions of excessive water pressure in wall-mounted boilers, and provide hot topics and hot content on the Internet in the past 10 days to help you better deal with this problem.
1. Reasons why the water pressure of the wall-hung boiler is too high
Excessive water pressure in wall-mounted boilers is usually caused by the following reasons:
| Reason | Description |
|---|---|
| The water replenishment valve is not closed | Failure to fully close the refill valve will allow tap water to continue to enter the system, causing water pressure to rise. |
| Expansion tank failure | The expansion tank has insufficient pressure or is damaged and cannot absorb excess water pressure in the system. |
| Temperature too high | As water temperature rises, the volume of water expands, causing pressure to rise. |
| There is air in the system | Unvented air can cause pressure fluctuations. |
2. Solutions to excessive water pressure in wall-hung boilers
For the above reasons, you can take the following measures:
| Solution | Operation steps |
|---|---|
| Close the water replenishment valve | Check that the refill valve is closed and make sure it is fully closed. |
| Check expansion tank | Check the pressure through the valve of the expansion tank. The normal pressure should be 1-1.5bar. If it is insufficient, it needs to be inflated; if it is damaged, it needs to be replaced. |
| Drainage and pressure reduction | Release some of the water through the drain valve of the wall-hung boiler or the exhaust valve of the radiator until the pressure drops to 1-1.5 bar. |
| Exhaust | Open the exhaust valve of the radiator to remove the air from the system. |

4. How to prevent excessive water pressure in wall-hung boilers
To avoid the problem of excessive water pressure in your wall-hung boiler, you can take the following precautions:
1.Check the water replenishment valve regularly: Make sure the water replenishment valve is closed to prevent tap water from continuously entering the system.
2.Maintain expansion tank: Check the pressure of the expansion tank once a year to ensure it is working properly.
3.Use heating wisely: Avoid frequent temperature adjustments in a short period of time to reduce system pressure fluctuations.
4.Pay attention to system exhaust: At the beginning of the heating season, completely purge the air from the system.
5. Summary
Excessive water pressure in wall-mounted boilers is a common problem that cannot be ignored. By understanding the causes, knowing the solutions, and taking preventive measures, you can ensure that your wall furnace operates safely and efficiently. If you encounter difficulties during operation, it is recommended to contact professional maintenance personnel to avoid more serious failures caused by self-operation.
I hope this article can help you solve the problem of excessive water pressure in your wall-mounted boiler and provide a practical reference for your winter heating!
