Combi boiler noise problem

Yes, try calling a central heating engineer. You'll find them in Yellow Pages.

That's C-E-N-T-R-A-L H-E-A-T-I-N-G E-N-G-I-N-E-E-R.

Make sure you have something called "money" to pay them with.

Good luck!

Get out the wrong side of the bed? This is a diy group and he asked a reasonable question!

Well, apart from this being a D-I-Y group, and that was a D-I-Y question... as I already mentioned, it's not my boiler. So I wouldn't be making the call or paying anyway. I'm sure you meant well, but it would have helped if you'd read the post before replying.

Back to the subject: I'd really appreciate any helpful advice that I could pass along. Thanks.

And this is UK.D-I-Y. Too difficult for you to understand?

Oh - someone who fixes heating for a living is a fitter. Not an engineer.

The last thing you want is someone from the Yellow Pages - the people who really can help don't bother advertising in there!

There are dozens of sources of noise however they seem to mainly occur on the cheaper boilers. Scaled secondary heat exchangers, duff diverter valves, air in system etc.etc.
