However, many users have reported that the floor heating is not hot, which directly affects the comfort of life. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the common reasons and solutions for underfloor heating, and provide structured data for reference.
1. Common reasons why floor heating is not hot

There are many reasons why the floor heating is not hot. The following are the issues that have been discussed most recently by netizens:
| Cause classification | Specific performance | Frequency of occurrence (last 10 days) |
|---|---|---|
| clogged pipes | The water flow is not smooth and the area is not hot. | 35% |
| Insufficient air pressure | System pressure is lower than normal | 25% |
| Thermostat failure | Unable to adjust temperature or display abnormality | 20% |
| Installation issues | Pipe spacing is too large or unevenly laid | 15% |
| other reasons | Such as power supply problems, valves not opening, etc. | 5% |
2. Solutions and suggestions
In response to the above problems, the following are the solutions recently shared by professional maintenance personnel and netizens:
1. Pipe blockage
Regular cleaning of floor heating pipes is key to preventing blockages. It is recommended to carry out professional cleaning every 2-3 years, especially if the floor heating system has been used for many years. Recently popular cleaning methods include pulse cleaning and chemical cleaning, which can be selected according to actual conditions.
2. Insufficient air pressure
Check the pressure gauge of the floor heating system. The normal value should be between 1.5-2.0bar. If the pressure is too low, you can manually increase the pressure through the water replenishment valve, or contact a professional to handle it. Netizens recently reminded that you need to operate slowly when pressurizing to avoid sudden pressure rises that may damage the pipeline.
3. Thermostat failure
First check whether the thermostat battery is exhausted, and secondly confirm whether the temperature setting is correct. If it still cannot be solved, it may be a sensor or circuit problem, and you need to contact after-sales service. Smart thermostats have become a hot topic recently, and many users have solved the problem of inaccurate temperature control after upgrading their devices.
4. Installation problems
If the newly installed floor heating is not hot, it may be caused by improper installation. It is recommended to contact the installation company to check the pipe laying density and circuit design. Recently, there have been many cases of uneven heating caused by excessive pipe spacing, which requires attention.
3. Recent popular floor heating problem cases
The following are specific cases that have been discussed more by netizens in the past 10 days:
| area | Problem description | solution |
|---|---|---|
| Beijing | After the floor heating is turned on, only the bathroom is hot and other areas are not. | Solve it after cleaning the pipes |
| Shanghai | Floor heating temperature cannot exceed 20℃ | Normal after replacing thermostat |
| Guangzhou | Some areas of the newly installed floor heating are not hot at all | Readjust pipe spacing |
| Chengdu | There is abnormal noise when the floor heating is working | Disappears after exhaust treatment |
4. Tips to prevent underfloor heating from not being hot
Based on recent expert advice and netizen experience, the following preventive measures are summarized:
1. Check system pressure and water quality before the heating season every year
2. Maintain ventilation around the thermostat to avoid inaccurate temperature sensing.
3. When not in use for a long time, the system water should be drained to prevent scaling.
4. Choose a regular installation company to ensure reasonable pipeline design
5. Consider installing a water filter to reduce the risk of pipe blockage
5. When does it require professional maintenance?
When encountering the following situations, it is recommended to contact professional maintenance personnel immediately:
1. The system pressure continues to drop and cannot be maintained
2. Multiple rooms are not hot at the same time, and the exhaust is ineffective
3. There is obvious leakage in the pipeline
4. Thermostat completely malfunctions
5. Newly installed floor heating does not heat large areas
Through the above analysis and suggestions, we hope to help solve the problem of "the floor heating at home is not hot". If the problem persists, it is recommended to contact a local professional floor heating maintenance service to ensure normal heating in winter.
