How to Bleed a Radiator?

Bleeding a radiator is a straightforward process that involves releasing trapped air to improve its heating efficiency. Here’s how to do it:

Steps to Bleed a Radiator

Turn off the heating: Allow the radiator to cool completely. This is important to avoid burns and to get an accurate reading on how well it's heating once you've finished bleeding it.
Prepare your workspace: Place a towel and a jug or container under the bleed valve of the radiator. The towel will catch any drips, and the jug will collect any water that is released during the process.
Locate and use the bleed key: Insert a radiator bleed key into the square slot of the bleed valve.
Open the bleed valve: Slowly turn the bleed key anti-clockwise. You will hear a hissing sound as trapped air escapes.
Wait for water to appear: Keep turning slowly until water starts to come out rather than air. At this point, quickly close the valve by turning the bleed key clockwise.
Repeat on all radiators: Do this for every radiator in your home, starting with the ones that are furthest away from the boiler.

Trapped air in radiators can hinder their performance, causing cold spots.
Bleeding a radiator helps to ensure efficient heating by allowing hot water to circulate fully.
A regularly bled radiator uses energy more efficiently, potentially saving on heating bills.

Keep the towel and jug positioned to prevent water damage.
If a radiator continues to feel cold after bleeding, consider re-bleeding it again.
If problems persist, consult a heating engineer.

By following these steps, you can easily bleed your radiators and ensure that they are working efficiently.
