Does your radiator feel cold at the top and warm at the bottom? If so, it’s likely that the problem is being caused by air that has been trapped in your radiator. Luckily, you should be able to fix the problem yourself by bleeding your radiator.

Bleeding a radiator is a fairly simple, safe and quick process. Basically it just means opening a small valve on your radiator to allow any trapped air to escape. Just follow our simple instructions below for a quick fix:

  • Before you bleed your radiator, it’s very important that you turn off your central heating at the main controls. This will prevent more air from entering the system.
  • Find the¬†bleed valve, this is usually located on one of the top sides of the radiator.
  • Place a cloth or a small bowl underneath the bleed valve to catch any leaking water. Also, wrap your hand in a cloth to shield your hand as any water that escapes from the radiator may be very hot.
  • Your radiators should have come with a small bleed key (or radiator key). If you can’t find the bleed key you should be able to buy a replacement at your local DIY store.
  • First you’ll need to locate the bleed valve. This will be a protrusion at the top of one side of your radiator. To bleed your radiator, insert the bleed key into this valve and carefully turn it anticlockwise (usually a quarter or half turn will do the trick). The air trapped in your radiator will start escaping with a hissing sound. When water begins to dribble out the valve you will know that all the air has been purged from the radiator.
  • Once water dribbles out of the valve you should tighten the valve back to it’s original position. Use the cloth to clean up any spills (be careful, though, as the water can be scalding hot).
  • Don’t forget to switch the central heating back on once you’ve finished bleeding the radiator. Check on your radiator after a couple of hours to ensure that the radiator has a uniform temperature all over it’s surface area and that there’s no more water leaking from the bleed valve. Problem solved!
