The technique to bleeding a radiator yourself


Bleeding a radiatorEvery now and then you may notice your radiator’s aren’t working as well as they should be. Perhaps they are cold towards the top and warm at the bottom? If this is the case, then it sounds like you need to bleed your radiators. You will probably be thinking “how do I do that then?”, well that is why we have put together the information in this post.

How to bleed a radiator:

  1. The first thing to do is turn off the central heating. This is a vital step, as the reason for the radiators not heating up properly is usually because of trapped air. Therefore, you don’t want to let anymore air into the system, so by turning the heating off this is preventing any additional air entering the radiators.
  2. Next, you must switch off the bleed valve. Usually, this is a small red handle found at the side of the radiator. If you are unsure as to the location of the bleed valve, be sure to check with a professional plumber.
  3. Following this, you must place a bowl or any object that can catch water underneath the radiator end, you don’t want water surrounding you on the floor!
  4. Now you are all set to start bleeding the radiators. Needless to say, you will need a radiator bleed key, if you happen to have lost yours, any local DIY shop will sell them such as B&Q. The bleed valve is usually situated at the top of the radiator, so once you begin slowly turning the bleed key you should hear air escaping. The job is complete once you have a continuous flow of water coming out. Jobs a good’un!

The next time you turn your heating on, you should notice a great difference in the heat emitted from the radiators. If you don’t fancy attempting this yourself, or this doesn’t fix the issue, feel free to give our central heating professionals in Sheffield a call on 01226 755661 today!
