How to bleed a radiator?

Some of the following are issues with radiators which can be resolved by bleeding your radiator.

1- trapped air. Over time, air can get into the central heating system, and because heat rises, it will cause air to bubble at the top of radiators.

This is an issue that commonly occurs with the radiator that is furthest away from the boiler and is fed by down pipework.

Trapped air in the top of the radiator panel can make it less efficient, and cause it to be unable to heat a room.

2- Radiators can also become very noisy when the pipework is full of air, and this is how you can see whether it needs to be bled.

Bleeding a radiator means that you are releasing the air from the panel. Sometimes, sludge might also be released with water from the unit if you are dealing with this problem.

When you do this, water can seep out of the radiator so ensure you have something to protect the floor and to collect the water.

It is important that the hot water and central heating in your home is turned off before you attempt to do this.

Bleeding the radiator requires the radiator key to be pressed into the release valve, which can cause water to come out of the panel. You will hear a release of air and water might come out of the radiator when this key is turned.

When less water starts to come out of the radiator and the air is no longer hissing, it is time to turn the key back to seal the valve.

3- Sludge might be in your system if the pipework is very corroded.

While this can be released through bleeding, it might be best to see a professional for this issue to keep your home safe.

This is something that happens with older radiators, and it might be a sign that the system needs to be replaced.

After you have bled the radiator, the pressure in your boiler will lower.

This is why you will need to learn how to re-pressurise the boiler before tackling the radiator.
