How to deflate the sunflower radiator
With the arrival of winter, many families begin to use heating equipment, and sunflower radiators are widely welcomed for their high efficiency and energy saving characteristics. However, the radiator may suffer from air blockage during use, resulting in reduced heating efficiency. This article will introduce in detail the deflation method of the sunflower radiator, and attach relevant data to help users solve the problem quickly.
1. Why do you need to bleed the radiator?

The accumulation of air inside the radiator will hinder the circulation of hot water and cause uneven heat dissipation. The following are common symptoms of air blockage:
| Symptoms | Possible reasons |
|---|---|
| The upper part of the radiator is not hot | There is air accumulation inside |
| The radiator makes the sound of water flowing | Mixed flow of air and hot water |
| Decreased overall heating effect | Hot water circulation blocked |
2. Steps to deflate the sunflower radiator
The following is the detailed deflation operation process:
| steps | Operating Instructions |
|---|---|
| 1. Turn off the heating system | Make sure the radiator is cool to avoid burns |
| 2. Find the bleed valve | Usually located on top of the radiator with holes for screws |
| 3. Prepare tools | Use a bleed key or slotted screwdriver |
| 4. Slowly unscrew the air release valve | Turn counterclockwise, and when you hear a "hissing" sound, the air is discharged. |
| 5. Wait for the water flow to stabilize | When water flows out, close the valve immediately |
| 6. Check the heating effect | Restart the system and observe whether the radiator heats evenly |
3. Precautions
Please pay attention to the following matters during the deflation process:
| Things to note | Description |
|---|---|
| Avoid over-tightening the valve | Prevent valve damage or leakage |
| Prepare water container | Prevent water from flowing onto floors or walls |
| Regular inspection | It is recommended to deflate the air once at the beginning of each heating season |
4. Frequently Asked Questions
The following are questions and solutions frequently encountered by users:
| question | Solution |
|---|---|
| Still not hot after deflating | Check whether the pipes are clogged or the system has insufficient water pressure |
| The valve cannot be turned | Spray a small amount of lubricant to avoid forced operation |
| Frequent need to deflate | It may be that the sealing of the system is poor. It is recommended to contact a professional for maintenance. |
5. Summary
Deflating the sunflower radiator is simple, but attention must be paid to details to avoid damaging the equipment. Through regular maintenance, you can ensure that your radiators operate efficiently and enhance your winter heating experience. If the problem persists, it is recommended to contact professional maintenance personnel for further inspection.
Through the guidance of this article, I hope you can easily solve the problem of radiator air blockage and enjoy a warm and comfortable home environment.
