What should I do if my boiler is making noise?
Your boiler should have a pressure gauge that’ll tell you whether the pressure is correct. If it’s low, you might have a leak in the system, in which case you need to locate and identify the problem. If you can increase the flow rate in your boiler you should be able to solve the problem, if only temporarily.
Why does my boiler make a clicking sound when I Turn on the tap?

Why does my boiler make a boiling kettle noise?
Kettling isn’t a process of retraining for your boiler because it fancies a career change, kettling is caused by a build-up of limescale or sludge on your boiler’s heat exchanger. This build-up restricts the flow of water in the heat exchanger, overheating the water, causing a noise like that of a boiling kettle to occur.
