How to pressurize a wall-hung boiler: operating instructions and precautions
As a common heating equipment in modern homes, wall-mounted boilers are inseparable from stable water pressure for their normal operation. If the pressure is insufficient, it may lead to a decrease in heating effect or even equipment failure. This article will introduce in detail the steps of pressurizing wall-hung boilers, common problems and related hot topics in the past 10 days on the Internet to help users solve problems quickly.
1. Wall-hung boiler pressurization operation steps
| steps | Operating Instructions |
|---|---|
| 1. Check current pressure | Observe the pressure gauge of the wall-mounted boiler. The normal range is 1.0-1.5Bar. If it is lower than 1.0, pressurization is required. |
| 2. Turn off the power of the wall-hung boiler | Ensure equipment is in shutdown state to avoid operational risks |
| 3. Find the water filling valve | Usually located at the bottom of the fireplace, it is a black or blue knob |
| 4. Slowly turn the water filling valve | Rotate 90 degrees counterclockwise and stop when you hear the sound of water flowing. |
| 5. Observe the pressure gauge | When the pressure reaches about 1.2Bar, close the water injection valve clockwise |
| 6. Restart the wall-hung boiler | Check whether normal operation resumes after powering on |
2. Frequently Asked Questions about Pressurization
| question | Causes and Solutions |
|---|---|
| pressure continues to drop | The pipe may be leaking and you need to contact a professional for repair. |
| Water injection valve cannot be opened | If the valve is corroded, try lubricating it or replacing the valve. |
| No change in pressure gauge | Check whether the tap water inlet valve is open or the pipe is blocked |

4. Precautions for pressurization
1.Safety first: Be sure to turn off the power before operation to avoid live work.
2.Fill water slowly: Rapid pressurization may cause water hammer effect and damage the pipeline.
3.Regular inspection: It is recommended to check the pressure gauge every month and perform comprehensive maintenance before the heating season.
4.Professional assistance: If repeated pressurization fails or abnormal noise occurs, contact after-sales service immediately.
5. Extended reading: Wall-hung boiler maintenance tips
1. Clean the heat exchanger once a year to prevent scale accumulation.
2. Check whether the exhaust pipe is smooth to avoid exhaust gas backflow.
3. When not in use for a long time, the water stored in the system should be drained to prevent freezing and cracking.
Through the above steps, users can easily complete the wall-hung boiler pressurization operation. If you encounter complex problems, it is recommended to refer to the device manual or contact the brand’s after-sales service. Proper maintenance can not only extend the life of the wall-mounted boiler, but also improve heating efficiency and save energy expenses.
