2. Detailed explanation of the steps for air pressure adjustment of wall-hung boilers
1.Check current air pressure value: The air pressure should be maintained between 1-1.5bar during normal operation. You can check it through the pressure gauge that comes with the wall-hung boiler.
2.Hydration operation process: If the air pressure is lower than 1bar, water needs to be replenished:
- Turn off the power supply to the wall-mounted boiler
- Locate the refill valve (usually the black knob)
- Turn counterclockwise until the pressure gauge displays 1.5bar
- Immediately close the valve clockwise
3.Pressure relief treatment method: When the pressure exceeds 2.5bar:
- Drain water through radiator vent valve
- Or contact a professional to drain the system
3. Comparison of air pressure parameters of wall-hung boilers of different brands
| Brand | Standard pressure value | Water replenishment temperature control method |
|---|---|---|
| power | 1.2-1.5bar | Automatic hydration |
| Bosch | 1.0-1.5bar | Manual knob |
| Rinnai | 1.2-2.0bar | electronic control |
4. Answers to users’ high-frequency questions
Q: Why does the pressure continue to drop after replenishing water?
A: Possible reasons:
- There is a leak in the system
- Expansion tank failure
- Automatic exhaust valve is damaged
Q: The air pressure is normal but the heating effect is poor?
A: It is recommended to check:
- Whether there is air accumulation in the radiator
- Is the water pump working properly?
- Is the temperature sensor accurate?
5. Safety precautions
1. Be sure to turn off the power when replenishing water to prevent idling damage to the water pump.
2. If the pressure exceeds 3bar, it must be stopped immediately and reported for repair.
3. Conduct professional testing at least once a year
4. Gas valves should be operated by certified personnel
Through the above structured data and operation guide, we hope to help you correctly adjust the air pressure of the wall-mounted boiler. In case of complicated situations, it is recommended to contact the brand’s after-sales service first. Reasonable air pressure adjustment can not only improve heating efficiency, but also ensure safety. This is also the core focus of recent hot discussions on the entire Internet.
