If you hear your boiler making strange noises, it can be worrying. However, there are several causes of a noisy boiler that are worth checking yourself, as you may be able to resolve the problem easily.
It is worth checking the boiler’s pressure gauge if the boiler is making a noise. If the gauge shows that the pressure is too low, follow the instructions in the manufacturer’s guide to top up the pressure.
A blockage in the flue can cause a whooshing noise. If you place your hand over the flue, you should be able to feel air passing. A blockage could be down to something being stuck in the flue, which may be easy to remove but if not, you should call an experienced engineer to investigate.
Air filters can become blocked and interfere with the functioning of the boiler. It is possible to remove some air filters for cleaning, so check this as you may be able to easily rectify the issue yourself. If your boiler does not allow for easy removal of the air filter, do ensure you call a trained engineer to do this for you.
If your circulation pump is running too fast, it may cause whirring sound. Check if your boiler has an option to slow down the circulation pump, but if your model of boiler does not have this option, you will need to call a heating engineer to deal with the matter for you.
Bleed the system
If your heating system is full of trapped air, it can cause some very strange sounds including whistling noises. If this is the case, you can easily remove the build-up of trapped air by bleeding the system.
Correct maintenance can prolong the life of your boiler. One elderly couple’s boiler recently only gave up after almost 50 years! Your boiler may not last that long, but regular services can help pick up any issues before they cause real problems or damage. Many experienced heating engineers can offer boiler servicing. For example, in Cheltenham boiler service is an option offered by http://www.hprservicesltd.com/cheltenham-boilers/boiler-service-cheltenham/
It’s definitely worth checking the above possible causes as you might just be able to handle the issue yourself, but if in doubt, do ensure you call a trained and experienced heating engineer.
