Bleeding RadiatorsIf you find that your radiators don’t seem to have the heat distributed around them evenly it may be because over time air has become trapped in them.  But don’t worry, this is something that you can solve yourself at home in no time at all by simply bleeding your radiators.

All radiators have a bleed valve on them which is located in one of the top corners, you’ll see that looks like a square shaft inside of a threaded plug.

You’ll need a radiator key to open the valve and let the air out, but don’t worry if you can’t find yours, or simply don’t have one, you can purchase a new key from any reputable DIY store for just a couple of pounds.

When you’ve got your key, grab yourself a cloth as well as you’re going to need one on hand to catch any water that trickles out when you open up the valve.

To bleed your radiator, you’ll first need to turn your heating off as you don’t want to burn yourself, and then using your radiator key turn the shaft anti clockwise by a quarter or a half turn, opening the valve.  Never turn it more than one complete turn!

You’ll know when you’ve opened the valve enough as you’ll hear a hissing noise as the trapped air from your radiator escapes, and when it’s all out water will start to trickle out of the valve.  As soon as the water appears you need to close your valve, this time turning the key clockwise to seal it back up.

Bleeding your radiators should be an infrequent task and if your finding you need to do this on a regular basis this may indicate that there are some issues or faults with your heating system and it’s then a good idea to call out a Heating Engineer to check your system thoroughly.
