It does mean I am spending time measuring rooms, calculating BTUs and radiator sizes and considering which boiler! At least I can find radiators of the same length as my existing 22 year old ones which then avoids some messy pipework as my CH pipes come out of the wall above the skirting board. What I do need to watch is some of the present day radiators can put out more BTUs than the old ones and care is needed not to over spec.
Then I will have an argument with whoever installs about (a) whether the gas pipe from meter to boiler needs to be bigger and (b) if it does the route it is to take! As for the former many fitters seem to automatically say you need a bigger supply but I understand that is not necessarily so and much depends on the boiler. I could be walking into the problem we have with Evohome in that not many installers properly know the system. Like Honeywell, Intergas have approved installers, but............!
As for boilers, and I will give him a plug!, Richard at The Intergas Shop has been very helpful with advice on what is preferable, advisable flow and returning settings etc. to ensure condensing works efficiently.
