Radiators are preparing to kick back into life after a summer-long absence. While you might not have turned your heating on just yet, it won’t be long before you rely on your radiators to keep your home or property nice and cosy during the colder winter months.
However, it’s common for radiators to make some strange noises at the start of the season.
It’s a relatively normal expectation that your radiators will operate quietly, which means any sudden noises are very noticeable.
You might find that they make a loud clicking noise or unexplained bangs.
While it’s completely normal for your radiator to make unusual noises, it’s best to keep on top of them.

“While radiators are usually quiet, they’re not designed to be totally silent all the time – there are the occasional creaks and groans that you come to expect,” said Just Radiators.
“These will often occur as the system is heating up, or when it’s cooling down again – the metal will contract and expand naturally, and will sometimes creak.
“Another common cause of noisy radiators is pipe warping. Radiator pipes are made of metal that contracts and expands as they’re heated and then subsequently cooled.
“This expansion isn’t considerable, and it’s a totally natural reaction, but on rare occasions, it can lead to the pipe itself warping, as its structural rigidity is compromised through stress.”
If your radiator noises are annoying you, the easiest thing to do is bleed them.
Bleeding radiators will help to get rid of any lingering air bubbles, which should stop the clicking noise.
You might have to bleed several radiators around the home to fully cleanse the system of air bubbles.
Failing that, it’s worth contacting a plumber; especially if you’re not sure whether the noises are caused by limescale build-up.
