Combi boiler noise problem

[osc]

It's a Ravenheat CSI 85AT. It was self-installed (well... not me actually I'm passing this along for someone else) about 2 years and has worked fine since.

The problem is that the boiler pump appears to be making quite a loud ticking noise (the volume varies) occasionally -- when turning on the hot tap, or when the central heating comes on. Although the pressure within the central heating loop is well within the range described in the manual when the noise is occurring, if he adds more water pressure (pushing it up to 2 bar) the noise disappears.

Does anyone have an advice on curing the problem. Is the pump actually the problem and would replacing it solve it?

Thanks in advance.

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.
