What should I do if the floor heating is not hot? Comprehensive analysis of causes and solutions
With the advent of winter, the lack of heat in geothermal heating has become a focus of concern for many families. This article combines hot topics and user feedback from the entire Internet in the past 10 days to sort out the common reasons and solutions for why geothermal heaters are not hot, and provide structured data reference.
1. Common reasons why geothermal heating is not hot
| Cause classification | Specific performance | Proportion (user feedback) |
|---|---|---|
| clogged pipes | The water distributor valve has a large temperature difference and is not hot locally | 35% |
| Insufficient air pressure | System pressure is lower than 1.5Bar | 28% |
| filter clogged | The inlet pipe is hot and the return pipe is cold | 20% |
| Thermostat failure | The display is abnormal or cannot be adjusted | 12% |
| other reasons | The floor covering is too thick and has not been cleaned for a long time, etc. | 5% |
2. Targeted solutions
1. Pipeline blockage treatment
• Close all valves of the water distributor and release water to flush each branch
• Use professional geothermal cleaning equipment (recommended to clean every 2 years)
• Check whether the pipes are obviously deformed or damaged
2. System pressure adjustment
| Pressure value (Bar) | Handling suggestions |
|---|---|
| <1.0 | Immediately replenish water to 1.5-2.0 |
| 1.0-1.5 | Observe 24-hour pressure changes |
| >2.5 | Pressure reduction via drain valve |
3. Filter cleaning steps
① Close the main water inlet and return valve
② Use a wrench to open the filter end cover
③ Take out the filter and clean it with a toothbrush
④ Reinstall it as it is and slowly fill it with water and exhaust it.
3. Summary of recent hot issues (last 10 days)
| Hot search keywords | search volume index | main areas |
|---|---|---|

4. Professional advice
1.Golden detection period: It is recommended to test the temperature between 6 and 8 o'clock in the morning, when the system operates most stably.
2.Temperature standard reference: The ground temperature should be in the range of 24-28℃, and the ideal room temperature is 18-22℃
3.Emergency treatment: If leakage is found in the pipeline, close the main valve immediately and contact professionals
5. Preventive maintenance calendar
| month | maintenance items |
|---|---|
| October | System water testing and pressure testing |
| November | Running the exhaust for the first time |
| March | Shut down system maintenance |
| June | Annual deep cleaning |
Through the above systematic analysis and solutions, we hope to help you effectively solve the problem of non-heating geothermal heating. If the problem persists, it is recommended to contact a professional floor heating repair service to avoid system damage caused by self-disassembly.
