During the colder months, everybody wants their home to be warm and cosy and for their home to stay that way throughout the duration of winter, but what if your radiators just refuse to heat up, what do you do then?

Knowing how to fix any little issues with your heating will mean your home can stay warm without having the expense of calling out a heating engineer.

Why does my radiator have cold spots?

This usually means your central heating system isn’t working efficiently. If you find that your radiator is heating up at the bottom and yet the top of it remains cold, the chances are you have air trapped in the system.

Radiators need bleeding when they have air trapped inside them. This trapped air stops warm water circulating around your radiator.

How to bleed your radiator

It’s recommended that you bleed your radiators once a year, even if they are working properly.

This is what you’ll need to bleed a radiator:

  • A radiator key
  • A cloth or bucket to catch any water
  1. Then follow our instructions on how to bleed your radiator:
    Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be hot to touch
  2. Use your radiator key to turn the valve at the top of the radiator and turn. You should hear a hissing sound. This is the trapped air escaping. Use your cloth to catch any water that comes out
  3. Retighten the valve once the hissing stops and only liquid comes out
  4. Turn your central heating system back on and check the pressure of your boiler
