Help please - LOUD thumping/banging noise coming from boiler pipes

[hsadat]

Hi Guys

For quite some time I have noticed loud thumping and banging noises coming from the boiler.

Before I have a professional to come and have a look at it. I was wondering if you guys could tell me the cause of the noise as shown in the video by following the link below.

I suspect its trapped air and the radiators may need bleeding ?


Much thanks for the help.

Boilers only make noises like that when there is an over heating issue.

What is causing the boiler to over heat?
Generally something restricting the flow of water through the boiler.

As for what that can be....numerous parts of the system.

It gets quite involved after that

What boiler, what type how old all this has a bearing. centralheatking

The water is boiling in the system first thing to check would be the pump has not failed
