I hear you CM,
That he may be, but he still needs one fitting

Yep agree, but it's nice to see the full picture, maybe if a cylinder was removed the cause would be the increase in pressure to taps. Always better to know the cause as well as the solution, even if it just helps someone find the answer through browsing the old posts and not posting!

I don`t know where the the water hammer is/was occurring, dodgy plumber may have convinced OP " OOH that`s better innit?. The OP is reporting what he has been informed,How do you know the noise stopped after the plumber turned down the mains tap
Water hammer does not occur all of a sudden unless related to a prob with air in the pipeline, if he has not had this before then after a boiler change I would suggest an air lock.Bambergaspipe said:corgiman said:[how would turning the mains pressure down til the noise stopped be

An air lock in mains pressure hot water pipework?

Unvented cylinder is it?

It has started since the new boiler was fitted, on the very day in fact!!
We don't have any hot water tank! in fact NO tanks at all!.
There was one radiator that he said had the trv at the wrong end as it was rattling like a good'un. this he replaced and has been no probs since.
It does NOT happen when the taps are used, more precisely when they are NOT being used.
(Unvented cylinder is it?) Don't know if it is or not!
How do you get air from the pipes, and how do you know which pipe.

you have a combi boiler
I am betting that the banging is still a water hammer, bet the fitter opened the stop cock fully when he had finished.
Again (sheesh) you need a pressure reducing valve fitted to the mains supply and the banging will stop
and it will not be an airlock

Obviously as you have an Ideal Isar HE35 combi
A silly thought now
I take it the filling loop has been turned off and that the pressure gauge is reading between 1bar cold and about 2bar hot rads? if this was left open and system has overpressurised to above 3 bar then this will make boiler bang like a pnuematic drill as the prv releases the excess pressure.This would be reduced by turning the stop tap down I would think!
Other than that check again all trv's on rads for directional arrows. If they have 2 then no probs, but if only 1 then as previous reply says I would think flow and return have been reversed.
Thanks for your help,
Would/could I get BG to do this (FREE) as its a result of them fitting the boiler?
Yes, the filling loop has been turned off and disconnected, also its set at about 1.5 bar.
When it was first decided to have this boiler their rep said we have a good water pressure, which he checked and said all was ok. 15 bar I think he said, but don't quote me on that.
This happens even when the heating is OFF.

I'm not tight, just a bit careful, just thought if they created it they can get rid of it.
