How to release air from radiator
With the arrival of winter, the frequency of use of radiators gradually increases, but many users report that the radiators are not hot or have uneven heat dissipation. By searching the hot topics and hot content on the Internet in the past 10 days, we found that "radiator deflating" is a high-frequency search term. This article will introduce in detail the steps, precautions and common problems of deflating the radiator to help you quickly solve the problem of the radiator not being hot.
1. The necessity of deflating the radiator
When the radiator is in use, air may accumulate inside, causing the hot water to fail to circulate normally, thus affecting the heat dissipation effect. The deflation operation can discharge air, ensure the circulation of hot water, and improve the heat dissipation efficiency of the radiator.
2. Steps to deflate the radiator
| steps | Operating Instructions |
|---|---|
| 1. Preparation | Close the water inlet valve and return valve of the radiator and prepare a screwdriver or bleed key. |
| 2. Find the bleed valve | Usually located on the top of the radiator is a small screw or valve. |
| 3. Deflation operation | Use a screwdriver or bleed key to turn the bleed valve counterclockwise until you hear a "hissing" sound (air being released). |
| 4. Close the bleed valve | When water flows out, immediately close the bleed valve clockwise. |
| 5. Check the effect | Open the water inlet valve and return valve and observe whether the radiator returns to normal heat dissipation. |
3. Precautions
1.Safety first: To avoid burns when deflating, it is recommended to wear gloves when operating.
2.Tool selection: Use a special deflation key to avoid damaging the valve.
3.Close in time: Once water flows out, immediately close the air release valve to prevent large amounts of water leakage.
4.multiple attempts: If the effect is not obvious after deflating once, you can repeat the operation.
4. Frequently Asked Questions
| question | Answer |
|---|---|
| What should I do if the air release valve cannot be tightened? | It may be that the valve is corroded. You can drop a little lubricating oil and tap it gently before trying again. |
| Is the radiator still not hot after deflating? | It may be that the pipes are clogged or the radiator is aging. It is recommended to contact a professional to check. |
| What should I do if the water flow does not stop when deflating? | Close the bleed valve immediately, check the valve for damage, and replace it if necessary. |
