Noisy Boiler

Why is your boiler making noises?

If your boiler is making noises, not only is it likely to frighten you if you’re home alone, but its symptomatic of a more serious issue. Although your boiler might seem to be working perfectly, it’s almost certain to break down in the near future. So, what are the noises to look out for and what is causing them?

  • Gurgling is a common sound to hear coming from your boiler, however if the noise is particularly loud, it can often be a sign of a deeper issue. You may have air trapped in a different part of the heating system (could also sound like whistling) and in this case you should try bleeding your radiators. Other reasons for this noise include low water pressure, a broken circulation pump or a frozen condensate pipe.
  • Whooshing sounds are often caused by blockages in the flue or air filter. These problems are relatively simple to fix and action should be taken quickly to avoid any further damage to the boiler.
  • Humming or whining sounds almost always require the help of a professional heating engineer. These sounds will buzz from inside your boiler and are commonly caused by a circulating pump set too fast, vibrating fans or loose components.

Frequently Asked Questions

  • Why is my boiler making noises?This could be a couple of things. Firstly, there may be air in the pipes, in which case you'll need to drain it from the system. It could also be trapped water caused by a broken pump or limescale on your heat exchanger. The safest thing to do is turn off your boiler and speak to a professional for advice on next steps.
  • What should I do if my boiler is making a gurgling, vibrating or whining noise?If your boiler is gurgling, bleed the system, check the water pressure and check the circulation pump. If it's vibrating, check the flue and air filter.
