How To Bleed A Radiator In Your Home

Chill talks you through it


We all remember that classic scene in Father Ted where Ted and Dougal go into hibernation so that they can survive the extreme cold of their house due to the high cost of heating during the winter - and sadly, this isn’t too far from many people’s realities.

You probably have some heat reducing routine that is in action by now. For many, it involves getting the throw blankets out of storage. Then rooting around in the wardrobe for the warmest fleece lined jacket they can find. All this in the hope that they can avoid turning on the central heating for as long as possible. But is there anything practical you can do to warm the house and lower the costs at the same time?

Here in Chill house we are always looking for ways to help you save money, usually through our home insurance money saving tips and suggestions. Our suggestion starts with a simple question, are your radiators working?

If your answer starts with "no, what now", then it might be time you thought about bleeding them.

What you need to bleed your radiator

  1. Access to the bleed valve.

  3. Kitchen towel or cloth to soak up water released from the radiator.

How to bleed your radiator

  1. Locate your bleed key/screw driver and bleed valve.
  2. Make sure the heating is turned off as to not introduce additional air into the system.
  3. Make sure the intake and exit valves are open.

  6. Close valve and repeat on any other radiators that you have identified as being faulty.
  7. Check your boiler pressure levels to ensure that you haven’t affected the overall pressure within the houses heating system. If this is the first time you have had to do this you should consult the instruction guide as provided by the manufacturers.
