If your radiators aren't heating up properly or they have cold spots, you might need to bleed them.
Don't worry - this is a simple fix that anyone can do. You'll find a guide below showing how to bleed a radiator in a few quick steps. Not only will it keep your house warmer, it will save you money too.
Radiators need bleeding when they have air trapped inside them. This trapped air stops warm water circulating around your radiator. That can make the radiator cold at the top, but warm at the bottom.
It means your central heating system isn’t working efficiently and it can take longer to warm up your room. It can also cost you money, as your bills will be higher.
You might also need to let out trapped air if you have noisy radiators which are making banging, clanking or gurgling noises.
It’s recommended that you bleed your radiators once a year, even if they are working properly.
