Follow this simple step-by-step guide to check and bleed your radiators:
1. ๐๐ฎ๐ซ๐ง ๐ฒ๐จ๐ฎ๐ซ ๐ก๐๐๐ญ๐ข๐ง๐ ๐จ๐ง
Turn your heating on and wait for all of the radiators in your home to warm up (the length of time may depend on how many radiators you have and the size of your home, so be sure to give yourself plenty of time).

Carefully check each radiator to ensure it has an even temperature across the whole surface area. If you do find any radiators that are cold at the top or hear any gurgling noises, itโs a good indicator that thereโs trapped air inside and that youโll need to bleed it.
Tip: We recommend wearing a thin pair of gloves when checking each radiator as they may be very hot.

Before you start bleeding any radiators, we recommend turning off your heating so the radiators arenโt too hot to touch

Locate the radiator bleed valve and ensure that a cloth or an old towel is placed below it to catch any water that may be released.
Tip: Every radiator has a bleed valve. Theyโre typically located at the top corner of a radiator and look like a round hole with a square inside.

If no water or air comes out when you bleed the radiator, then the valve could be blocked with paint. Close the inlet and outlet valve at each end of the radiator, then remove the screw from the centre of the bleed valve. Insert the radiator key into the bleed valve and slowly turn it anti-clockwise (a quarter of a turn should be enough). You should hear a hissing sound as the air escapes.
Tip: We recommend having a bucket handy to catch any spurting water, just in case you open the valve too far.

Once the hissing sound stops and water starts to leak out, turn the key clockwise to close the valve.

Repeat this process for each radiator that needs bleeding in your home. Once youโve finished doing this, youโll need to check the pressure of your boilerโs water pressure gauge.
If the boiler pressure is too low (below 1 bar), youโll need to repressurise the system. If the pressure is normal (between 1 and 2 bars), you can switch your heating on and check that your radiators are now heating up as they should.
