Rumbling/Clunking noise coming from Boiler

[Ali Purkis]

Hey,

First off, I'm unsure whether I've posted this in the correct forum but it seemed the most relevant from the list shown.

I seem to be getting a rumbling/clunking noise coming from our combi boiler when we run hot water in the bathroom. As it is making this noise, the needle on the pressure gauge is jumping around. The boiler is downstairs in our kitchen, and when I run hot water in the kitchen sink it sounds normal and fine.

Is this what is known as kettling?

Cheers,
Ali

This often happens when there is a partial blockage in the plate heat exchanger or a pump issue you need a GSRI to diagnose the fault and carry out repairs or replacement. Regards kop
