The majority of radiators do a great job at warming up a house, office or any other type of building. However, some that don’t work as well as they are supposed to and when this happens, the cold kicks in.
Keeping your radiators healthy and in tip-top condition will help make sure they work as efficiently as possible.
If you’re having problems with your radiator, it could be for a number of reasons but the most common issue with radiators is trapped air.
Trapped air inside a radiator means that the water can’t circulate through the whole radiator. You won’t only be cold, you’ll be wasting money on heating that isn’t working effectively.
In our latest blog, Phil Birchenough, talks through how to bleed your radiator with a step-by-step guide and explains why it’s important.
There are a few tell-tale signs that your radiators might need to be bled. The most common sign is the top half of the radiator is cold and the lower half is warm.
This means that air is trapped at the top and therefore the warm water can’t circulate to the top half of the radiator where the air is.
Radiators that are making strange, rattling, banging and gurgling noises can also indicate there is air in the system.
Once you’ve identified that you need to bleed your radiators, all you’ll need is a radiator key and a cloth to catch any water that may come out!
When you bleed your radiators, there is a potential for some water to come out along with the trapped air. Turning your heating off will not only reduce the water pressure in the radiator but it will make sure that any remaining fluid isn’t hot. This will eliminate the risk of injury.
You will need to use a radiator key loosen the valve at the top of your radiator. As you start to loosen it, the radiator should make a hissing noise. Don’t panic, all this means is that trapped air is escaping from the radiator. At this point, there might be some excess water that comes out as well so make sure you have a cloth at the ready to catch it!
Once the hissing noise has stopped, it means that all the air that was trapped in the radiator, has now escaped. You now need to retighten the radiator valve.
You can now turn the central heating back on. When you do this, make sure to check the pressure gauge. Sometimes, bleeding your radiators can cause a drop in pressure. It’s a simple fix, all you need to do is use your filling loop to top it back up! If your radiators heat up evenly throughout the whole radiator, you’ve fixed the problem.

To keep your radiators in good working order, you should bleed them at least once a year. This will enable any gradual build-up of air to be released and for your radiators to work as effectively as they can.
If bleeding your radiator doesn’t solve the problem, there could be another issue and if you’re not sure what it could be, read our blog about the most common boiler problems.
