How to replenish water in wall-hung boiler
As a common heating equipment in modern homes, wall-mounted boilers are inseparable from proper water pressure for their normal operation. Replenishing water is an important part of daily maintenance of wall-mounted boilers, but many users are not familiar with the operating steps and precautions. This article will introduce in detail the correct method of replenishing water in a wall-mounted boiler, and attach relevant data for reference.

2. Check whether there is any water leakage in the system.
3. Prepare the appropriate tools (such as a refill key or screwdriver).
| Check items | normal range | Exception handling |
|---|---|---|
| water pressure gauge reading | 1.0-1.5bar | If it is lower than 1.0, you need to replenish water. |
| Pipe connection | No leakage | If water leakage is found, report it for repair |
2. Detailed explanation of water replenishment steps for wall-hung boilers
1.Find the refill valve: Usually located at the bottom of the wall-mounted boiler, marked with the words "replenish water".

| phenomenon | Possible reasons | Solution |
|---|---|---|
| Rapid pressure drop | System leaks | Contact a professional |
| Unstable pressure | There is air in the pipe | Perform exhaust operation |
