Domestic boiler noises and what they actually mean

Why is my domestic boiler making funny noises?

A domestic boiler can be a funny old thing, especially when it makes those weird and lively noises. It’s perfectly normal for heating to make the odd strange noise, especially after a long hot summer of being switched off. If the commotion shows no signs of quietening down, however, then it may be a good idea to investigate the issue.

From annoying gurgling noises to a loud, banging racket, here’s what your domestic boiler could be trying to tell you.   

Gurgling and bubbling

If you hear a gurgling sound, this could signify a build-up of air trapped within your radiators. Bleeding them will most likely help to resolve this issue but if the bubbling continues, it could be a sign of something more serious. We would generally recommend a call to your professional heating engineer who will most likely be able to diagnose the problem.

Whistling

Also known as ‘Kettling’, your central heating system may whistle when there is a build-up of debris and sludge. A powerflush will more than likely rectify this problem and have your domestic boiler back up and running in no time. To find out more about a powerflush by Direct Heating Installations, why not have a read of this handy guide?

Buzzing or Humming

If your domestic boiler is making a loud humming or buzzing sound, this can often mean there is a problem with the heating elements found within the system. It’s not really something you should be trying to fix yourself so for this type of scenario, we’d recommend getting in touch with Direct Heating Installations.

Clunking and banging

When water passes through central heating pipes, they expand and contract due to the heat. If these pipes haven’t been installed properly to start with, it can lead to further problems and cause loud banging noises to occur. Our heating engineers will be able to diagnose whether your existing pipework needs to be refitted. We can also carry out the required remedial work and put a complete stop to those annoying loud noises.  

Dripping

If a domestic boiler is making dripping or trickling noises, this may indicate a leak usually within the system. It’s also often because the boiler pressure is too high and can, as a result, wear down the actual boiler components. In such cases as this, it’s highly recommended that you contact a professional heating engineer.

Tapping

And finally, one other common domestic boiler noise is the sound of tapping from the system. It’s more than likely caused by a part being fitted incorrectly or potentially, a build-up of limescale. If you live in a hard water area, this is the most likely cause of a limescale build-up and so a powerflush to the system will soon put things right again.
