What to do if the water pressure of the wall-hung boiler is low
Wall-mounted boilers are important equipment for winter heating in many homes, but they may encounter problems with low water pressure during use, resulting in poor heating effects or even equipment shutdown. This article will give you a detailed analysis of the causes and solutions of low water pressure in wall-mounted boilers, and provide structured data for reference.
1. Reasons for low water pressure in wall-hung boilers
Low water pressure in wall-mounted boilers is usually caused by the following reasons:
| Reason | Description |
|---|---|
| System leaks | Leaks in pipes or valves causing water pressure to continue to drop |
| Automatic exhaust valve failure | The air in the system cannot be discharged normally, affecting the water pressure. |
| The water replenishment valve is not fully closed | The valve is not closed tightly after replenishing water, causing slow pressure release. |
| Expansion tank failure | The air bag is damaged or has insufficient pressure and cannot maintain normal water pressure. |
2. Solutions to low water pressure in wall-hung boilers
When the water pressure is too low, you can follow the following steps to troubleshoot and solve the problem:
| steps | Operating Instructions |
|---|---|
| Check pressure gauge | Confirm the current water pressure value (normal range 1-1.5bar) |
| Check for leaks | Carefully check pipes, valves, radiators, etc. for leaks |
| Hydration operation | Find the water replenishment valve and slowly replenish water to the normal pressure range |
| Exhaust treatment | Open the radiator exhaust valve to remove air from the system |
| Check expansion tank | Test the expansion tank pressure and replace if necessary |
3. Recommendations for maintaining water pressure in wall-hung boilers
In order to keep the water pressure of the wall-hung boiler stable, it is recommended to take the following precautions:
1.Regular inspection: Check the pressure gauge reading once a month to ensure it is within the normal range.
2.Pay attention to hydration: Operate slowly when replenishing water to avoid sudden increase in pressure and damage to the equipment.
3.System maintenance: Ask professionals to conduct a comprehensive inspection of the system before the heating season every year.
4.Timely maintenance: When problems such as water leakage are discovered, they should be dealt with immediately to prevent small problems from developing into major failures.
4. Frequently Asked Questions
| question | Answer |
|---|---|
| What should I do if the water pressure drops to 0? | Stop using it immediately, check the system for serious leaks, and contact professionals if necessary |
| Does the pressure drop quickly after replenishing water? | Indicates that there is a leak in the system and a comprehensive inspection of pipes and connections is required. |
| How to deal with excessive pressure? | Appropriately drain water through the radiator exhaust valve to reduce pressure to avoid exceeding 2 bar. |
5. Professional maintenance suggestions
If the problem is still not solved after the above operations, it is recommended to contact professional maintenance personnel. The following situations require professional intervention:
1. The system has continuous pressure relief for unknown reasons.
2. Expansion tank failure
3. The water supply system does not work properly
4. The wall-mounted boiler frequently reports water pressure fault codes.
Through the above content, I believe you have a comprehensive understanding of the problem of low water pressure in wall-mounted boilers. Regular maintenance and correct operation are key to ensuring the normal operation of the wall-hung boiler.
