What should I do if the earth heater is not hot? ——Comprehensive troubleshooting and solution guide
As temperatures plummet in winter, lack of heat in earth heaters has become a common problem faced by many families. This article combines hot discussions and expert advice on the Internet in the past 10 days to organize structured solutions for you to help you quickly restore heating.
1. Frequently Asked Questions Checklist
| Question type | Specific performance | probability of occurrence |
|---|---|---|
| poor circulation | Partial radiator hot/partial cold | 35% |
| clogged pipes | The overall temperature of the heating is insufficient | 28% |
| Not enough pressure | Boiler stalls frequently | 20% |
| gas problem | Difficulty in ignition or abnormal flame | 12% |
| other reasons | Thermostat failure, etc. | 5% |
2. Step-by-step solution
1. Check the circulatory system (for poor circulation)
• First try to exhaust: Use a screwdriver to open the exhaust valve at the top of the radiator until water comes out and close it.
• Check whether the water pump is running. There should be a slight vibration when touching the water pump housing.
• Adjust the manifold valve to ensure balance of each branch
2. Clean the pipes (for blockage problems)
• Remove the filter for cleaning after shutting down the system
• Use professional cleaning agents to circulate the pipes
• Serious blockage requires contacting a professional for high-pressure cleaning
3. Pressure adjustment method
| Pressure value | Status judgment | Processing method |
|---|---|---|
| <0.8bar | Not enough pressure | Pressurize to 1.5bar through the water supply valve |
| 1.5-2bar | normal range | maintain status quo |
| >2.5bar | Pressure is too high | Pressure relief via exhaust valve |
3. Focus on recent hot issues
According to the analysis of discussion data across the entire network, there are three recent high-frequency issues:
1."The heating in the old house suddenly stopped working": Air blockage is often caused by the aging of pipelines. It is recommended to exhaust air first and then check the tightness of the pipelines.
2."Newly installed heating effect is poor": Commonly caused by unreasonable system design. It is necessary to review the matching between the number of radiators and the room area.
3."It's hot during the day and cool at night": Mostly related to thermostat settings or operation during peak and valley electricity price periods
4. Professional maintenance suggestions
•Annual maintenance:Six basic maintenance items, including system cleaning and seal inspection, should be completed before the heating season.
•Consumables replacement cycle:
| Part name | Recommended replacement cycle |
|---|---|
| filter screen | 1 time per year |
| water pump mechanical seal | 3-5 years |
| gas nozzle | 5-8 years |
5. Emergency treatment plan
If you encounter a sudden lack of heat, try the following steps:
1. Close all radiator valves
2. Start one by one starting from the latest group
3. Wait 10 minutes after each group is turned on to observe the temperature changes.
4. After locking the fault point, close the corresponding branch to ensure heating in other areas.
Warm reminder:If you still can't solve the problem after self-examination, it is recommended to contact professional HVAC personnel to handle it. Keeping the heating system in good condition can increase thermal efficiency by 20%-30% and effectively reduce energy consumption.
