My friend is in the process of having his central heating system overhauled, including having a conventional, heat-only boiler replaced. The make of the new boiler is 'ideal.' The new boiler has already been installed and a new external pipe has also appeared, running from the gas meter outside, along the wall of the house, then through this to the boiler itself. It is a copper pipe that has been mounted to the outside wall with plastic fittings. I would guess the diameter of the pipe to be 22mm, although it appears that there is a 15mm pipe running within that.
I have lots of questions!
I would like to know why there is a new pipe, where there was none before? (friend has just spoken to plumber, who says it did in fact replace an existing pipe, which apparently wasn't big enough)
Why is it a pipe-within-a-pipe? (isn't that very expensive? - and the narrower, internal pipe looks like standard 15mm - how could it be replacing anything narrower than that?)
Is the pipe is going to stay uncovered along the outside wall or should we expect the plumber to cover it with some insulation? (it looks very odd, it would be better if it were painted the same colour as the house)
Should we just trust the plumber and let him get on with it? (he is corgi-registered, prompt, very pleasant, perfectly approachable, although leaves it to us to phone him, rather than giving updates on his progress)
Thanks very much for any feedback!
