Sounds produced by electric radiators and what they mean

Ultrad smart electric radiator in living room

As we’ve stated numerous times in our other blogs, electric radiators offer a host of benefits over alternative heat emitters. For example, they provide heat where and when it’s needed, they don’t require expensive maintenance, they are reliable, and they are extremely energy efficient.

However, because the radiator body is made of aluminium, clicking noises can sometimes occur. These are caused by the expansion of the aluminium as the radiator heats up, but don’t worry – clicking does not indicate a fault on the unit.

Indeed, any device made predominantly of metal is prone to make a noise. Besides, water-filled radiators can gurgle and bubble, oil-filled radiators can make a ticking sound, and the electric element in tubular towel rails can fizz and hiss (unsurprisingly, not unlike the noise of a kettle).

None of these are a cause for any concern. However, if your electric radiators persist in making a noise and this is causing a disturbance, try the following:

  • Verify that the wall brackets are fitted correctly. The brackets must be installed following the cardboard template provided with the unit.
  • Confirm that the screws at the top of the brackets are there; these screws hold the unit to the wall brackets and prevent the aluminium from expanding. If the screws are present, remove them, lift the unit and put it back. If the unit was installed properly in the first place, this should go smoothly. Once you have put the unit back, reinstall the screws, making sure the metallic tab touches the aluminium body.

If your unit continues to make a noise, record a video with the sound clear on the recording and the thermostat’s display in view, and send it to our technical department. This will help us identify where the noise is coming from and determine how to fix it.
