Erm Meldrews mate, I don't build or design boilers so no that statement obviously does not include my work.
You state that you have fitted 40 of these units in 2 years and that you have had few failures, does that mean you rarely work on them? Have you ever tried changing any of: PRV, plate h/e, main h/e, CH isolation valves or diverter (ISAR) ? Well I have...every bloody week. None of them are easy jobs as everything is so badly designed and crammed together. One can hardly reach the PRV to test it during a service as there is so much other crap in front of it.
I would be interested in asking you what you think of them in another 2 years when they are all costing your customers bags of money in replacement parts. My firm removed and scrapped at least 3 ICOS/ISAR's all installed for less than 3 years between February and March this year as the cost of constantly replacing parts on them was making the council that owned them very angry. The council in question (one of London's biggest) stopped installing them due to their unreliability and are now putting Vaillants in.
I think that you are either on a wind up, or that you are an Ideal shareholder or something. I'm sure that no-one who has fitted these boilers over a 2 year period would truly be happy with them.
As for your diatribe on British industry and why I should buy British, I'll ask you this: would you have bought a Rover car during the 1990's and been happy about it? If you know anything about cars then the answer would be no. If something is cr@p but made in Britain, its still cr@p. What about the Potterton Puma, fine piece of British engineering there...
Was the re-badged Biasi which Ideal sold for a while designed in Britain? Doubt it.
Or, maybe (just maybe) all of the professionals who post on this forum about how rubbish Ideal boilers are wrong, and you alone are right...
