Your radiators should be hot from top to bottom throughout your home. If they aren’t getting hot at the top,  there is air trapped in the system. You can fix this easily by following our step by step instructions to bleed your radiators. You can also watch this video explaining how it’s done.

All you need to get started is a radiator bleeding key and an old cloth to catch water.

  1. Before you begin, make sure your heating is turned off and your radiators have completely cooled down.
  2. Insert the radiator bleeding key into the valve at the top of your radiator. Hold the cloth underneath to catch the small amounts of water that will leak out.
  3. Slowly turn the key anti-clockwise., You should hear the air coming out. . When water starts to leak from the valve, turn the key clockwise again to close the valve.

Bleeding radiators can remove pressure from your heating system so you may need to check your boiler pressure gauge. If necessary, top up the pressure in your boiler.

If you’re not sure how to tell if you need to top up your boiler, you can find out in our step by step guide.
