How to bleed a radiator...

If your radiators are not as hot as they should be this can often be caused by air that is collected inside them. Over time your radiators may begin to feel hot at the bottom and cold at the top this is a common symptom.

  1. Locate the bleed valve usually found on either the top right, left or back of radiator.

  2. With the system turned off and cooled down use a bleed key to open the valve half a turn.

  3. Hold an old cloth below the valve and once the air has been removed and water starts to be released then shut the valve and repressurise the system if necessary.

  4. Test heating and check radiators. If problems continue please feel free to get in touch via phone, email or using the contact us forms at the bottom of this page.

        

If you find your radiators are hot at the top and cold at the bottom this could be caused by a build up of magnetite sludge and your system may benefit from a powerflush.
