Bleeding a radiator is one of the simplest DIY tasks you can do, but there is a method to bleeding your radiators to ensure you get the maximum benefit to your central heating.
It is a good time of year to check your central heating is working properly, to ensure you won’t be without it when you need it when the weather gets colder. Bleeding your radiators is a good place to start, and we explain how, as well as which radiator to bleed first.
From time to time, air can get trapped in your central heating system, which means you need to bleed your radiators. The best way to check if you have air trapped is to switch on your central heating to maximum and allow the radiators to heat up to their full temperature.
Check each radiator carefully, and feel if there are any temperature differences across the surface of each radiator. If it feels cool at the top, and warm at the bottom, then it is likely you have air trapped, and it needs bleeding. Remember to check all the radiators and bleed all those that need.
The radiator to bleed first
Before you start, ensure that your central heating is switched off, and start with a downstairs radiator that’s the furthest from your boiler. Work methodically, moving to the next closest to the boiler, and repeat the process on the next floor.
How to bleed a radiator
All you need is a brass radiator key (or a flathead screwdriver) and a cloth to catch any drips of escaping water. Please ensure your heating system is switched off and had a chance to cool down before starting this job.
Once you’ve bled all your radiators, switch on your central heating and you should find that all of your radiators are heating up evenly and fully. If this is not the case, or if you find you are having to bleed your radiators regularly, it’s probably worth getting in a professional heating engineer to look for any deeper problems.
