How to bleed your radiator
Bleeding your radiator every so often could potentially save you energy and improve your heating performance.
Radiator bleeding is the process of letting any trapped air escape from your home’s heating system, which will increase heating performance, get rid of those rattling sounds, and ultimately save you money on your heating bill in the long run.
When do I need to bleed my radiators?
To assess whether you need to bleed a radiator or not, start by turning on your heating system and allowing it to start warming up your radiators. While they’re warming up, listen for any clanking or rumbling sounds - this could very well be pockets of air rushing through your heating system.
The second sign to analyse whether your radiators need bleeding is once the radiators are sufficiently heated, run your hands along the top of the radiator. If it’s cold at the top and hot at the bottom, there’s likely to be a build-up of air in the system. Again, please take extra care here as the radiators will be hot, so be sure to use gloves.
We recommend regularly checking your radiators and bleeding them as necessary however a rule of thumb is bleeding them every year.
If you have to repeatedly bleed radiators, then discuss this with your installer when the boiler is serviced as there may be an underlying problem.
