How to reduce water pressure in wall mounted boiler
Wall-mounted boilers are important equipment for winter heating in many families, but too high or too low water pressure will affect their normal operation. Recently, the issue of water pressure adjustment in wall-hung boilers has become a hot topic, with many users reporting equipment failures due to improper operation. This article will detail how to safely and effectively reduce the water pressure of a wall-hung boiler and provide structured data for reference.
1. Common causes of excessive water pressure in wall-hung boilers
Excessive water pressure is usually caused by:
| Reason | Description |
|---|---|
| The water replenishment valve is not closed | Failure to close the valve in time after replenishing water resulted in continued water inflow |
| temperature change | Increased water temperature causes water pressure to naturally increase |
| System failure | The pressure sensor or safety valve is damaged |
2. Steps to reduce water pressure
The following are the specific steps to reduce the water pressure of the wall-hung boiler:
| steps | Operating Instructions |
|---|---|
| 1. Check the pressure gauge | Confirm whether the water pressure exceeds the normal range (usually 1-2bar) |
| 2. Close the water replenishment valve | Make sure the refill valve is fully closed |
| 3. Exhaust operation | Release excess pressure via radiator vent valve |
| 4. Drainage treatment | If the pressure is still high, open the drain valve to drain out some of the water. |
| 5. Restart the device | After adjustment, restart the wall-hung boiler to observe pressure changes. |
3. Precautions
Please pay attention to the following matters during operation:
| Things to note | Detailed description |
|---|---|
| Security protection | Wear gloves when operating to avoid burns |
| drainage container | Prepare water containers to avoid getting the ground wet |
| Professional assistance | If multiple adjustments are ineffective, it is recommended to contact after-sales service |
| Regular inspection | Check pressure gauge readings monthly |
4. Water pressure standards of wall-mounted boilers of different brands
The normal water pressure range of mainstream brand wall-mounted boilers is slightly different:
| brand | Normal pressure range (bar) | Danger threshold (bar) |
|---|---|---|
| power | 1.0-1.5 | >3.0 |
| Bosch | 1.2-1.8 | >2.8 |
| Rinnai | 1.0-2.0 | >3.2 |
| Ariston | 1.2-1.6 | >2.5 |
5. Frequently Asked Questions
Regarding the issues that users are most concerned about:
| question | solution |
|---|---|
| Pressure drops too quickly after draining | Check the system for leaks |
| Pressure gauge pointer is unstable | It may be that the pressure sensor is faulty and needs to be replaced. |
| The refill valve cannot be fully closed | The valve seal may be aging and require repair |
Through the above methods, most problems of excessive water pressure in wall-hung boilers can be solved. It is recommended that users maintain their equipment regularly and contact professional maintenance personnel promptly when encountering complex problems. Proper pressure regulation not only extends the life of your equipment, but also ensures heating efficiency and safe use.
