Noisy Boiler

A noisy boiler is not only inconvenient, it is also annoying. This noise is often referred to as “kettling”. A boiler that is making hissing or banging noises must be fixed immediately. The noise could be a symptom of a bigger problem waiting to unfold. It is best to get a boiler repair done as soon as possible. Don’t underestimate this problem and think that it can be fixed easily. Boiler service and repair must be done by qualified gas safe registered engineers. However, there are a few things you can do to check and even alleviate the problem.


Noisy Boiler

The most common cause of kettling is scale in the heating system. Scale build up can cause hot spots making steam bubbles that cause the noise. A quick do- it- yourself solution to this is a chemical descaler or a noise silencer. You can buy this in most DIY stores. You simply pour the silencer in your header tank and it breaks down the scale. Make sure you read the label and instructions.

However, the long term solution to a noisy boiler is really draining the water system first. This is a job for a certified gas safe registered engineer, and must not be done DIY by someone without the competency and training. Your local engineer will power flushed and descaled.

Another cause of a noisy boiler is a slow pump. A slow pump doesn’t move the water fast enough as it boils, causing the banging noise. In this case, it is best to get an engineer to check it properly.

A faulty thermostat could also be causing the noise. Note that the replacement must only be done by a qualified engineer.
