One of the simplest things that can cause you to lose heat in your radiators, and cost you more money, is trapped air in the heating system. Bleeding your radiator is the solution, but just how do you go about doing that?

HOW DID THAT AIR GET IN THERE?

Air can enter your heating system a number of ways, but the most common ways are down to faulty parts on the system (like a failing pump for example), or corrosion in the system causing hydrogen to be released via chemical reaction.

 

When these gases are released into the system they naturally travel to the highest part of it they can (like air trapped in a bottle), and settle there, taking up space which could otherwise be filled with hot water, causing your radiator to be cool near the top.

 

HOW TO BLEED YOUR RADIATORS

You will need;

  • An old towel, cloth or some kitchen roll to catch any water which comes out
  • A bleed key; we recommend purchasing a multi-purpose 4-way key which features square, triangle and other shaped keys for a variety of utility cupboards and bleed valves
  1. First, turn on your heating and make sure all of your radiators are on. Then go radiator by radiator to determine exactly which ones require bleeding by feeling towards the top of the radiators for cold spots
  2. Once you know which ones have trapped air, locate the bleed valve. At the top of your radiator on one end you will find a bleed valve with a smaller inner piece to turn and open to release the trapped air
  3. Using your bleed key, position your cloth gently around the valve and slowly open it. You will hear a hissing and the sound of air being released. By gradually releasing the air you will be more prepared for once the air is all gone and water tries to escape.
  4. Once water starts spilling into your chosen cloth/towel, close of the bleed valve until firmly shut

 

All done! Move on to the next radiators (if there are any) and repeat the process until finishes.
