How to deflate an old radiator
With the arrival of winter, many families begin to use radiators for heating. During the use of old-fashioned radiators, it often happens that the radiator is not hot or is not hot locally. This is often due to the accumulation of air inside the radiator, which prevents the normal circulation of hot water. This article will introduce in detail the method of deflating old-fashioned radiators to help you quickly solve the problem of not heating.
1. Why do you need to deflate the radiator?
During the use of the radiator, air will gradually accumulate inside the radiator, forming an air blockage. Air blockage will hinder the normal circulation of hot water, causing the radiator to be partially or completely unheated. Therefore, regularly deflating the radiator is an important step to ensure the normal operation of the radiator.
2. Preparation work before deflation
| Tool name | Purpose |
|---|---|
| screwdriver | For unscrewing the air release valve |
| Water container | Used to catch the water flowing out during deflation |
| towel | Used to wipe water splashed during deflation |
3. Detailed explanation of deflation steps
1.Turn off heating system: Before deflating, turn off the power supply or valve of the heating system to ensure safety.
2.Find the bleed valve: The air release valve of old radiators is usually located on the top or side of the radiator and 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.Unscrew the air release valve: Use a screwdriver to gently unscrew the air release valve. If you hear a "hissing" sound, it means the air is being discharged.
5.Wait for the water flow to stabilize: When the air is exhausted, water will flow out, and the air release valve can be closed at this time.
6.Check radiator: Restart the heating system and check whether the radiator returns to normal operation.
4. Common problems and solutions
| question | Solution |
|---|---|
| The air release valve cannot be opened | Use lubricant or lightly tap the valve to help loosen it |
| The radiator is still not hot after deflating the air | Check the heating system for other faults, such as clogged pipes |
| Air release valve leaking | Close the valve and check whether the sealing ring needs to be replaced |
5. Precautions for deflating
1.Safety first: Be sure to turn off the heating system when deflating to avoid burns.
2.Avoid over-tightening: Bleed valves are usually small and over-tightening may cause damage to the valve.
3.Regular inspection: It is recommended to check whether the radiator needs to be deflated before the start of winter every year.
6. Maintenance tips for old radiators
In addition to regular deflation, routine maintenance of old radiators is also very important. Here are some tips:
1.Clean radiator surface: Dust and dirt will affect the heat dissipation effect. Wipe the surface of the radiator regularly with a soft cloth.
2.Check pipe connections: Make sure there is no leakage or looseness in the pipe connections of the radiator.
3.avoid occlusion: Do not place large furniture or debris in front of the radiator to avoid affecting heat dissipation.
Through the above methods, you can easily solve the deflation problem of old radiators and ensure the heating effect in winter. If you encounter any difficulties during operation, it is recommended to contact professional maintenance personnel for processing.
