How to deflate a copper-aluminum composite radiator: analysis of hot topics on the Internet
Recently, with the arrival of the winter heating season, the issue of outgassing of copper-aluminum composite radiators has become a hot topic on the Internet. Many users have reported that the radiator is not hot or is not hot locally, which may be related to the accumulation of internal gas. This article will combine the hot content of the past 10 days to provide you with a detailed analysis of the deflation method of copper-aluminum composite radiators and provide structured data reference.
1. Why do you need to deflate the radiator?
During use of the copper-aluminum composite radiator, air may accumulate inside, resulting in poor hot water circulation and thus affecting the heating effect. The purpose of deflating is to expel this air to ensure smooth flow of hot water and improve the heat dissipation efficiency of the radiator.
| Problem phenomenon | Possible reasons |
|---|---|
| The upper part of the radiator is not hot | internal gas accumulation |
| The radiator is not hot overall | Insufficient system pressure or air blockage |
| There is a sound of water flowing from the radiator | There is air inside |
2. Steps to deflate the copper-aluminum composite radiator
The following is a hotly discussed method for deflating copper-aluminum composite radiators on the Internet, which combines professional advice and user practical experience:
| steps | Operating Instructions |
|---|---|
| 1. Prepare tools | Prepare a flat-blade screwdriver or special deflation key, and a water container |
| 2. Close the radiator valve | Close the water inlet valve and return valve to ensure that the system is at rest |
| 3. Find the bleed valve | Usually located on the top side of the radiator, there is a small screw hole |
| 4. Slowly unscrew the air release valve | Turn the screw counterclockwise and hear a "hissing" sound to indicate that the air is being discharged. |
| 5. Watch the water flow | When water flows out, immediately tighten the air release valve clockwise |
| 6. Restore the system | Open the water inlet valve and return valve and check the radiator temperature |
3. Things to note that are hotly discussed across the internet
According to the hot topics of discussion in the past 10 days, the following matters have attracted much attention:
1.Safety first: The water temperature may be high when deflating, so be careful to prevent burns.
2.Avoid over-watering: Just release the air. Excessive water release will affect the system pressure.
3.Regular inspection: It is recommended to check once in the initial and middle stages of heating.
4.system pressure: If the problem is not solved after deflating, you may need to check whether the system pressure is normal.
4. Frequently Asked Questions (Q&A)
| question | Answer |
|---|---|
| What should I do if the air release valve cannot be opened? | You can try slight tapping or lubrication with WD-40, but do not use violence. |
| Is the radiator still not hot after deflating? | It may be a system circulation problem, it is recommended to contact a professional |
| How often does it need to be deflated? | Usually 1-2 times a heating season, depending on the specific situation |
5. Expert advice and user experience
Based on recent discussions in professional forums and social media, experts recommend:
1. Choose a day with warm weather to perform the deflation operation to avoid a sudden drop in indoor temperature.
2. For users of high-rise buildings, it is best to consult the property management company to understand the system pressure before deflating.
3. If deflating the air several times still does not solve the problem, the radiator may be installed at an incorrect slope.
Experiences shared by users include:
- You can use your mobile phone to take videos when deflating, so you can easily observe the water flow.
- Prepare a rag to prevent water from splashing on the wall
- Two people cooperate to operate more efficiently
6. Summary
Deflating copper-aluminum composite radiators is a simple but important maintenance operation. Correctly mastering the method can effectively improve heating efficiency. Through the structured data and hot content analysis of this article, I hope it can help you easily solve the problem of air blockage in the radiator and stay warm in winter.
