Powerflush is not a requirement of a new installation. Each boiler manufacturer will specify in the MI's what is required to maintain the manufacturers warranty. Also depends what was on the estimate.

Wouldn't mind hearing the full story on this one and not just little bits. Even better to hear both sides of a story.

so it was not a new system. It was a new boiler on current system.

Didn't say it was a new system, said it was a new installation, boiler installation. Starting to see why you had issues.

Good Luck.

Confused. Sorry if this comes over a little strongly but Simon is trying to help.

yes it did come over strongly. I am not an "awkward customer" I am trying to find out facts. I do not want to re write whole story. Could take years.

I believe the system should have been power flushed before the new boiler was connected, this doesnt appear to be done and therefore amonst other major problems will invalidate the warranty.

Without the full story we can't give you any further advice as we simpy do not know enough to give anything solid, please tell us, as these bits and bobs mean nothing to us.

Photos, boiler make, sizings, did they do heat calcs, what did they specify in their quote, did they replace the radiators?

A new boiler wont make a house hotter, a boilers output is limited by the radiators it is fitted too.

without this sort of information then you can't quote us on anything given.
and also I'm personally unwilling to help further without it.

you need to state your case, full facts to get a sensible answer, down to you now

just to clarify, as already stated: there is no requirement to power flush a new or existing system by any manufacturer that I am aware of. It should be flushed ie system filled, allowed to run up to temp with a cleanser in the system, then drained via a hose pipe. After this filled up and an inhibitor dosed to prevent corrosion.
powerflushing is specified depending on water quality, but this should be in the quote and not assumed to be taking place unless specified.

i would raise this with OFTEC and go from there.the firm haven't really done much wrong from a legal or regulation point of view, providing the boiler was correctly commissioned and the work complys with building regulations. Not sure how OFTEC handle complaints so would be interested to hear their response.

hope you had a lot of work done for that money...

It was meant to come over strongly.

I really struggle with 'I want help, but I'm not going to tell you the full story'. Any help given on snippets of information won't be of the slightest help. It seems as you are editing the 'story' to suit your purposes and use it as ammunition against the contractor.

I'll help everybody I can but won't be taken for a mug.

Good luck.

One thing I want to add, and it was only mentioned by the OP as a brief point. The fact that the pipes step one size after the boiler output is not a bad thing at all, and often happens. As heating engineers we have a rough idea of how many KW's a given pipe size will supply (however the figure varies on water velocity and temperature).

So sometimes it is necessary to step up a size after the boiler. Sometimes we step up several sizes to a 'header'. So do not take this as a bad point until it has been looked at by another heating engineer. Remember the heat exchanger is often a restricted flow size to the rest of the system anyway, and all that will happen is the water velocity will increase.

"I now have major problems with the job" at no point in the OP have you told us of how you've called them and explained this to them...

Looks like the excellent forum members have solved another problem :smile:
