How to deflate a new radiator

As winter approaches, the frequency of use of radiators gradually increases. Although new radiators are efficient and energy-saving, air blockage problems will inevitably occur during use, resulting in a decrease in heating effect. This article will introduce in detail the deflation method of new radiators to help you easily solve this problem.

1. Why do we need to deflate the radiator?

How to deflate a new radiator

When the radiator is in use, air will accumulate in the pipes, causing air blockage. Air blockage will hinder the flow of hot water, causing the radiator to be partially or completely unheated. Therefore, regular air bleeding is a key step to ensure efficient operation of the radiator.

2. Preparation work before deflation

Tools/MaterialsPurpose
screwdriverUsed to open the air release valve
Water containerUsed to catch the water flowing out during deflation
towelUsed to wipe up leaked water

3. Steps to deflate the new radiator

1.Turn off heating system: Before deflating, make sure the heating system is turned off to avoid burns caused by hot water splashing.

2.Find the bleed valve: The air release valve of new radiators is usually located on the top or side of the radiator. It is a small screw-shaped valve.

3.Prepare water container: Place the water container under the air release valve to prevent water from flowing to the ground.

4.Slowly unscrew the air release valve: Use a screwdriver to slowly unscrew the air release valve counterclockwise. A "hissing" sound indicates that the air is being discharged.

5.Wait for the water flow to stabilize: When the air is exhausted, water will flow out. At this time, continue to drain the water for a few seconds to ensure that the air is completely exhausted.

6.Close the bleed valve: Tighten the air release valve clockwise and wipe away the leaked water with a towel.

7.Check radiator: Restart the heating system and check whether the radiator heats evenly to ensure successful deflation.

4. Common problems and solutions

questionSolution
The air release valve cannot be openedSoak in lubricating oil for a few minutes before trying again, or ask a professional to handle it.
The radiator is still not hot after deflating the airCheck whether the pipes are blocked or contact the heating company
There is too much water when deflatingClose the bleed valve immediately and check whether the system pressure is too high

5. Precautions for deflating

1.Safety first: Avoid direct contact with hot water when deflating to prevent burns.

2.Regular inspection: It is recommended to check the radiator once a month and deflate it in time to ensure the heating effect.

3.Avoid frequent deflation: Frequent deflation may cause the system pressure to drop, affecting overall heating.

4.Professional help: If the problem is not solved after deflating it by yourself, it is recommended to contact professional maintenance personnel.

6. Advantages of new radiators

Compared with traditional radiators, new radiators have the following advantages:

FeaturesAdvantages
Energy saving and efficientHigh thermal efficiency, saving energy
Beautiful and elegantModern design, suitable for various decoration styles
Easy to cleanSmooth surface, not easy to accumulate dust

By following the steps above, you can easily deflate your new radiator to ensure effective winter heating. If you encounter any problems during operation, it is recommended to consult a professional in time to avoid damage caused by improper operation.
