How to deflate a wall-hung boiler

Recently, with the arrival of the winter heating season, the frequency of use of wall-hung boilers has increased significantly. Many users have reported that wall-hung boilers are not hot or make loud noises. Most of the reasons are related to the fact that the gas in the system is not exhausted. This article will introduce in detail the correct way to deflate a wall-mounted boiler, and attach data on hot topics across the Internet in the past 10 days to help users better solve heating problems.

1. The necessity of venting the wall-hung boiler

When the wall-mounted boiler is used for a long time or is started for the first time, air will accumulate in the pipes, resulting in poor hot water circulation and affecting the heating effect. The bleed operation removes air from the system and ensures efficient operation of the wall-hung boiler.

2. Steps to deflate the wall-hung boiler

1.Turn off the power to the wall-hung boiler: Ensure safe operation and avoid the risk of electric shock.

2.Find the bleed valve: A small screw or knob usually located on top of the boiler or at the highest point of the radiator.

3.Preparation tools: Use a flat-blade screwdriver or a special deflation key, and place a water container underneath.

4.Slowly rotate the release valve: Rotate counterclockwise, stop when you hear a "hissing" sound, and close the valve after the water flow stabilizes.

5.Check pressure gauge: The pressure may drop after deflation, and water needs to be replenished to 1-1.5bar (refer to the instruction manual).

4. Precautions

1. When deflating, avoid water splashing onto the circuit board, which may cause a short circuit.

2. If the air is still not hot after being released several times, check whether the pipe is blocked or the water pump is faulty.

3. It is recommended that professionals conduct a comprehensive inspection of the wall-hung boiler before heating every year.

5. User FAQs

Q: The wall-hung boiler still doesn’t work after deflating?

A: It may be that the pressure is too low or there is a gas supply problem. You need to check the pressure gauge and restart the equipment.

Q: How to deal with the leakage of the air release valve?

A: If there is slight water leakage, you can tighten the valve. If the water leakage continues, you need to replace the sealing ring or contact after-sales service.

Summary

Correct deflation is a key step to ensure the efficient operation of the wall-hung boiler. Combined with recent hot topics, it can be seen that winter heating issues have attracted much attention. If the problem is not solved after operation, it is recommended to contact professional maintenance personnel in time to ensure a safe winter.
