It’s coming to that time of year again. The mornings are cold and dark, making it even harder to wake up, and the nights are quickly drawing in. All you want is to wake up and come home to a lovely toasty home and feel all snug.

Before the ‘Big Switch On’ it’s important that you bleed your radiators in order to release trapped air and increase the efficiency of your heating system. Follow our fuss free steps to get rid of those cold spots for a cosy home and cheaper energy bills!

Step 1 – Switch On

Turn the heating on and wait until your radiators are fully heated.

Step 2 – Identify

Now that the pressure has built up inside the radiator you will need to check each one to see if all parts of the radiator are emitting heat. If you notice that a radiator has cold spots along the top of the panel it will need bleeding in order to remove the air bubble trapped inside.

Step 3 – Prepare

You need to ensure that your heating system is turned off as the radiators need to be cool enough for you to touch. You also need to make sure that you have a radiator key or a flat-head screw driver and a cloth to hand.

Step 4 – Bleed

  • Fit the radiator key or screwdriver into the groove
  • Hold a cloth around the radiator key/screwdriver and another underneath the valve to catch any drips
  • Slowly turn the radiator key/screwdriver anti-clockwise
  • If air is released you will hear a hissing sound
  • Following this release, liquid will begin to leak from the valve
  • Quickly turn the valve clockwise to close

Stage 5 – Pressure

Once your radiators have been bled, check the pressure gauge on your boiler. If the pressure is too low it will need to be topped up.
