How to exhaust air if the floor heating is not hot?
Lack of floor heating is one of the common problems in winter, and poor exhaust is often the main reason. This article will give you a detailed analysis of the reasons why the floor heating is not hot and the exhaust method, and provide structured data to help you solve the problem quickly.
1. Common reasons why floor heating is not hot
Underfloor heating may be caused by a variety of factors. The following are common causes:
| Reason | Specific performance |
|---|---|
| There is air in the pipe | Some areas are not hot and the sound of water flow is obvious |
| filter clogged | The overall heating effect is poor and the water flow is slow |
| Water pump failure | Poor system circulation and uneven temperature |
| Improper thermostat setting | The temperature cannot reach the set value |
2. How to judge whether exhaust is needed
If the floor heating has the following conditions, it is likely to need to be vented:
| phenomenon | Possible reasons |
|---|---|
| Some rooms are not hot | There is air obstruction in the pipe |
| hear the sound of water flowing | The air is not exhausted |
| Temperature rises and falls | Circulatory system is unstable |
3. Detailed explanation of floor heating exhaust steps
Exhaust is a key step to solve the problem of underfloor heating. The following is the specific operation method:
| steps | Operating Instructions |
|---|---|
| 1. Turn off the floor heating system | Make sure the system is at rest when exhausting |
| 2. Find the exhaust valve | Usually located at the end of a manifold or pipe |
| 3. Prepare water receiving tools | Prevent water from overflowing during exhaust |
| 4. Slowly open the exhaust valve | Hearing a "hissing" sound indicates the air is being released |
| 5. Watch the water flow | After the water flow stabilizes, close the exhaust valve |
| 6. Restart the floor heating system | Check whether the heating is back to normal |
4. Exhaust precautions
During the exhaust process, please pay attention to the following points to avoid operational errors:
| Things to note | Description |
|---|---|
| Avoid frequent exhaust | Excessive venting may cause system pressure to drop |
| Check pipe tightness | Prevent water leakage after exhaust |
| Observe temperature changes after exhaust | Make sure the issue is resolved |
5. Other reasons and solutions that may cause the floor heating to not be hot
If the floor heating is still not hot after exhausting the exhaust, it may be caused by other problems. You can refer to the following solutions:
| question | Solution |
|---|---|
| filter clogged | Clean or replace filter |
| Water pump failure | Contact a professional for maintenance |
| Pipe scaling | Clean floor heating pipes regularly |
6. Summary
Underfloor heating is usually caused by insufficient air in the pipes or poor system circulation. Most problems can be solved with proper venting. If it still cannot improve after exhausting, it is recommended to contact professional maintenance personnel for further inspection. Regular maintenance of the floor heating system can effectively prevent similar problems from occurring.
I hope this article can help you quickly solve the problem of underfloor heating and make your winter warmer and more comfortable!
