Why is my radiator making strange noises?


HPE, covering Uddingston and surrounding areas can offer you many services from installing a new boiler, to fixing your radiators. It is actually quite common for radiators to make some noise though, and not all should be a cause of concern. In fact, you can often do small jobs to stop the noise yourself.

Noise Types:

Whistling


This noise is made when the water flow rate through the radiator is too high. To solve the issue, turn the radiator fully on by twisting the taps anti-clockwise.

Ticking


It is entirely normal to have a ticking radiator- it is simply the radiator warming up, or cooling down. Sometimes noise may come from under the floor. This is likely to be a result of pipes expanding and rubbing on the flooring, or joists. However, normally this should not be a cause of concern/ worry.

Tapping


Tapping noises can be caused by a thermostatic radiator valve being incorrectly installed. If you have had to relocate your radiator, or you have had a new one installed, then the problem could be that the valves have been incorrectly swapped over. You may want to get this rechecked, if you cannot find another source for the issue.

Bubbling/ gurgling


Bubbling or gurgling noises are also a popular occurrence, but fortunately it can normally be fixed without a need for extra assistance, or expertise. With the correct tools, you could stop the irritating bubbling in just a few minutes!


Bleed the radiators


A radiator making a lot of noise is likely to have some air trapped inside it. In order to diagnose this problem, turn the radiator on and after a while, feel its temperature. If it is hot at the bottom, yet cold at the top, then you will need to bleed it.


Bleeding the radiators could release this air and stop the noises. To let the air out, all you need is a radiator key. For step-by-step advice, you can read online guides, such as this one 'how to bleed your radiators,' provided by 24/7 Home Rescue.


If you are having to bleed your radiators frequently, there is probably a leak somewhere in your central heating, and plumbing system. This will need to be located and fixed. Once remedied you should add some anti-corrosion inhibitors into the central heating system to prevent the problem repeating itself.


If you have a combi boiler, then once you have bled your radiators, you should check the pressure gauge. This can be found on the front of your boiler. With water being released from the system, it is possible that you will need to add more water to your boiler. Your boiler owner’s manual will contain instructions on how to do this, if you are unsure. You can normally find a new boiler manual online, if you are unable to locate yours at home. After this has been done, you can turn your heating back on. Your radiators should now be performing a lot better.
