How to deflate the floor heating vent valve
The floor heating system provides us with a comfortable indoor temperature in winter, but after long-term use, air may accumulate in the pipes, causing the heating effect to decrease. At this time, the air needs to be discharged through the bleed valve. This article will introduce in detail the operating steps, precautions and solutions to common problems of the floor heating vent valve.
1. The function of the floor heating vent valve
The main function of the floor heating vent valve is to discharge the air in the pipe to ensure smooth circulation of hot water and improve heating efficiency. If there is air in your floor heating system, it can cause the following problems:
| question | performance |
|---|---|
| Uneven heating | Some areas are hot and some areas are not. |
| noise | There is a sound of water flow or bubbles in the pipe |
| Increased energy consumption | System efficiency decreases and electricity or gas consumption increases |
2. Operation steps of floor heating vent valve
The following are the specific operating steps of the floor heating vent valve:
| steps | Operating Instructions |
|---|---|
| 1. Turn off the floor heating system | Make sure the floor heating system is turned off to avoid burns |
| 2. Find the bleed valve | Usually located at the highest point of the manifold or pipe |
| 3. Prepare tools | Prepare a screwdriver or special air release key, and a water container |
| 4. Slowly unscrew the air release valve | Gently loosen it counterclockwise. When you hear a "hissing" sound, it means the air is being discharged. |
| 5. Watch the water flow | When water flows out, it means that the air has been exhausted, close the valve immediately |
| 6. Check the system | Restart the floor heating and check whether the heating returns to normal |
3. Precautions
During the floor heating venting process, you need to pay attention to the following points:
| Things to note | Description |
|---|---|
| avoid burns | The water in the pipe may be hot when deflating, so be careful when operating. |
| Prevent water leakage | When the release valve is opened, use a container to catch the water flowing out |
| Do not over-tighten | Opening the bleed valve too much may cause damage to the valve or leakage. |
| Regular inspection | It is recommended to check the air release valve once a year before heating |
4. Common problems and solutions
During the floor heating venting process, you may encounter the following problems:
| question | Solution |
|---|---|
| The air release valve cannot be opened | Spray a small amount of rust remover and wait a moment before trying again |
| Heating is still not ideal after deflation | Check whether the water distributor valve is fully open, or contact a professional |
| Air release valve leaking | Close the valve, check whether the sealing ring is damaged, and replace it if necessary |
5. Frequency of floor heating venting
The frequency of underfloor heating venting depends on usage and water quality. The following are recommended deflation frequencies:
| Usage | Recommended frequency |
|---|---|
| Newly installed floor heating | Must be deflated before first use |
| normal use | Bleed air once a year before the heating season |
| Areas with hard water | Check every six months and deflate if necessary |
6. Summary
Floor heating venting is an important operation to maintain the floor heating system, which can effectively improve heating efficiency and extend the service life of the system. Through the introduction of this article, I believe you have mastered the correct operation method of the floor heating vent valve. If you encounter a problem that cannot be solved, it is recommended to contact professional maintenance personnel for processing.
Regular maintenance of the floor heating system will not only save energy, but also provide you with a more comfortable winter living environment. Hope this article helps you!
