How to Bleed your radiator and ensure that you are getting the most out of it

how to bleed a radiatorIf your radiator is not at a level temperature throughout and feels cool at the top and warmer towards the bottom.  It could be that gas and/or air is trapped in your radiator, stopping it from heating the radiator fully.  You can fix this yourself without having to call anyone out like a plumber/central heating technician. This will save you a bit of cash and it doesn’t take very long.  Doing this you will realise how much of a difference it will make to the efficiency of your radiators in your home (this in turn will save you a bit of cash also).

This is a safe way to bleed your own radiators and it doesn’t take that long!

  1. Firstly, you need to turn the heating on and get all the radiators on and working.  You may need to go round to each radiator individually and turn them up.
  2. Once the radiators are all going, check each one to see if the entire radiator is heating up. Careful not to scold yourself.  Make a note of which ones are not heating up correctly. Which ones have cool spots, these are the ones that will need to be bled.
  3. Then before you start bleeding the radiators, TURN OFF THE CENTRAL HEATING! This is an important step!
  4. To bleed older radiators you need a radiator key, but you can use a flat head screw driver with newer or more modern radiators. If you don’t have a radiator key, you can pick them up at a good DIY store.
  5. Locate the Bleed valve, this is mainly found on one side of the radiator.  You will need to protect the area and yourself, so put a cloth or a bowl under the valve to catch any water.

CAUTION – The water that comes out might be hot. So you might want to protect your hands.

  1. Insert the key into the bleed valve, turn it (about a ¼ turn) anti clockwise. The air or gas in the radiator will start escaping and you will be able to hear it making a hissing sound. Once water starts leaking out instead of air, this means that all the trapped air or gas has escaped.  So re-tighten the valve the other way to close it off.
  2. Repeat this with each radiator you noted that needs bleeding.
  3. Then turn your central heating back on. Check on your radiators after a while and each radiator should be heating up all over the radiator.

Enjoy The Warmth!
