Understanding different Worcester Bosch boiler noises

The boiler is one of the most relied on pieces of equipment in the home. From hot water to heating, we rely on the boiler for day to day life. And that’s why a boiler breakdown can be so difficult to deal with. The early signs of a boiler issue include boiler noises. But how can you determine between ordinary boiler noises, and potential problems? Well, here at Mark Vernon Heating and Plumbing, we are leading boiler experts. As a result, we have produced this guide to the different boiler noises to be aware of.

Understanding different Worcester Bosch boiler noises

Boilers make a variety of noises, and this is to be expected. From heating elements rapidly heating water, to old pipes and radiators, the central heating system can be quite noisy. So how can you tell whether these noises are problematic, or not? Well, there are several different types of noises, including:

  • Clunking noises- these are often called ‘kettling’ noises, and are caused by an accumulation of calcium carbonate (limescale) on the heat exchanger. This can block the flow of the water, resulting in more steam, which can lead to banging or clunking noises.
  • Whistling noises- if your boiler is making a whistling noise, this could also be as a result of kettling. This is because the trapped steam can begin to whistle. However, air can be trapped for reasons other than limescale build up, so its important to have this checked out. Releasing the trapped air is a simple repair task, and it can help rule out any potential problems at the same time. Whistling noises may also be caused by a loss of water pressure.
  • Gurgling noises- if your boiler is making gurgling noises, there could be a blockage, or a build up of sediment at the bottom of the boiler. You may also have a frozen condensate pipe, and this pipe will need to be thawed.
