Some time ago I had a problem with my Vokera 24 so got a corgi engineer to come fix it, out of curiosity I enquired about the price to replace it and he told me he would have to do all the gas pipe-work from the front to the back of the house, due to the regulation size changes on pipework and so at that point decided it was beyond my means.
I have had another problem with the boiler and this time it has been condemned by both the british gas engineer and also his supervisor. They did quote a price to replace it but at the same time stated I could get the job done much cheaper by a private engineer at which point I mentioned the pipe sizes and they answered that it doesn't matter.
Now I'm confused, I think I would rather trust bg than the guy I had before due to a couple of mistakes he made but wondered if anyone can shed further light on it for me.
The present boiler has been in for 9/10 years and so would be whatever pipe sizes they used back then, so has it changed and is it compulsary? I have found a brand new boxed Vokera 28 and wondered if an engineer would be able to just slot it onto my present fittings, the handbook and all specification is shared by both models but am i just grasping at straws? would appreciate any advice.
thanks in advance
