Hi
Our old Potterton Netaheat 16-22 is still pressing on, even though it's around 20 years old, but I'm thinking it may be time to replace it for all the obvious reasons.
The cost of gas isn't going to go down much and the efficiency of these new boilers is hopefully higher than the Netaheat, so the running costs should be lower. I'm guessing a replacement is going to be around ?2000 mark fitted, so I need to work out how long it would take to pay off that cost in terms of savings in running costs.
I wondered if anyone has any suggestions for where I can get some numbers to fill out all these vague feelings!
Finally, does anyone has any experience of running one the new condensing combis in a fairly large 3 storey house. ISTR the old combis weren't thought to be too good in such circumstances, but I'm sure things have changed now. Anyone have any boiler recommendations? I know some boilers are easier to work on than others and some are more reliable, etc.
