What to do if the wall-hung boiler overheats?
Wall-mounted boilers are important equipment for modern home heating, but they may encounter overheating problems during use. This article will give you a detailed analysis of the causes, solutions and preventive measures of wall-hung boiler overheating to help you quickly solve the problem.
1. Common causes of wall-hung boiler overheating failures
Boiler overheating is usually caused by:
| Reason | Specific performance |
|---|---|
| Water pressure is too low | Insufficient water pressure in the system results in poor circulation and inability to dissipate heat in a timely manner. |
| Water pump failure | The water pump does not work or the speed is insufficient, and the hot water cannot circulate normally. |
| Temperature sensor failure | Unable to accurately monitor water temperature, causing overheating protection to activate |
| System clogged | Blocked pipes or radiators, blocking hot water circulation |
| Gas pressure too high | Burns too vigorously and produces too much heat |
2. Solutions to wall-hung boiler overheating problems
When the wall-hung boiler overheats, you can follow the following steps to troubleshoot and solve it:
| steps | How to operate |
|---|---|
| 1. Check water pressure | Make sure the water pressure is between 1-2bar. If it is too low, add water. |
| 2. Check the water pump | Listen to the sound of the water pump running and turn the pump shaft manually if necessary |
| 3. Check the temperature sensor | Use a multimeter to test whether the resistance value is normal |
| 4. Check system patency | Check valves, pipes and radiators one by one for blockage |
| 5. Adjust gas pressure | Contact a professional to adjust the gas valve opening |
| 6. Restart the system | After troubleshooting, reset and restart the boiler |
3. Measures to prevent wall-hung boilers from overheating
In order to avoid the occurrence of overheating failure of the wall-mounted boiler, it is recommended to take the following preventive measures:
1.Regular maintenance: Ask professionals to conduct inspection and maintenance before the heating season every year.
2.Keep your system clean: Clean the filter and pipes regularly to prevent the accumulation of impurities.
3.Monitor water pressure: Develop the habit of regularly checking the water pressure and keep it within a reasonable range.
4.Pay attention to the usage environment: Make sure there is good ventilation around the wall-hung boiler to avoid high temperature environments.
5.Set the temperature appropriately: Do not set the water temperature too high. It is generally recommended to be between 60-70℃.
4. Professional maintenance suggestions
If the problem still cannot be solved after the above troubleshooting, we recommend:
1. Immediately turn off the power supply and gas valve of the wall-hung boiler to prevent further damage.
2. Contact the manufacturer’s after-sales service or professional maintenance personnel for on-site inspection.
3. Do not disassemble important components by yourself to avoid safety hazards.
4. Keep maintenance records to facilitate future maintenance and warranty services.
