How to vent floor heating
After the floor heating system is used for a long time, air may accumulate in the pipes, causing the heating effect to decrease. This article will detail how to bleed floor heating to help you restore the heating efficiency of your floor heating.
1. Why do you need to vent the floor heating?
The air in the floor heating pipes will block the flow of hot water, causing insufficient heating in some areas. Deflating air can discharge the air in the pipe, ensuring smooth circulation of hot water and improving the heating effect.
2. Preparation work before deflation
Before deflating, you need to prepare the following tools:
| Tool name | Purpose |
|---|---|
| deflate key | Used to open the bleed valve on the floor heating manifold |
| towel or container | Catch the water that comes out when deflating |
| screwdriver | Auxiliary tool for removing the manifold cover |
3. Deflation steps
1.Turn off floor heating system: Before deflating, turn off the power supply or gas valve of the floor heating to ensure that the system stops running.
2.Find the water separator: Floor heating water distributors are usually installed in hidden locations such as kitchens, bathrooms or balconies. Find the water distributor and open the cover.
3.Identify the bleed valve: There are usually one or more bleed valves on the water distributor, which are shaped like small screws and need to be opened with a bleed key.
4.Start to deflate: Place a towel or container under the deflation valve, and use the deflation key to turn the deflation valve counterclockwise until you hear a "hissing" exhaust sound. Wait for the air to drain out and the water flow to stabilize, then close the bleed valve clockwise.
5.Check heating effect: After deflation is completed, restart the floor heating system and observe whether the heating effect improves.
4. Precautions
| Things to note | Description |
|---|---|
| avoid burns | The water flowing out during deflation may be hot, so pay attention to protection |
| Prevent water leakage | Make sure the air release valve is closed tightly to avoid water leakage |
| Regular inspection | It is recommended to check and deflate every year before the heating season. |
5. Frequently Asked Questions
Q: What should I do if the floor is still not hot after deflation?
A: It may be that the pipe is blocked or the water pump is faulty. It is recommended to contact professional maintenance personnel for inspection.
Q: Do I need to close the valves in all rooms when deflating?
A: No, just close the floor heating main valve.
6. Summary
Venting the floor heating is an important step in maintaining the floor heating system and can effectively improve the heating effect. With the guidance in this article, you can easily complete the deflation operation. If you encounter complex problems, it is recommended to contact professionals in time to handle them.
