Hello All,
I have an ICOS M3080 24kw system boiler on its last legs. The Heat exchanger has started leaking and the boiler is now occasionally failing to fire up. As the heat exchanger would be costly to repair, and as the boiler is around 10 years old, it wouldn't make economical sense to get it repaired as I'm sure you will agree.
However, I am now in to minds whether I should move to a combi or stick with a gravity system. The house has 2 bedrooms upstairs, 2 reception rooms, bathroom + kitchen. In total we have 6 single panel radiators. We use a washing machine & gas cooker. The bathroom has a shower, and a crappy pump on the wall, so going combi would give us essentially better pressure upstairs, as well as save some space from the airing cupboard.
The question I have is would I need to have the 15mm gas pipe connection upgraded to a 22mm? If 15mm, are there any particular manufacturers that still do this? Would a 24KW output still be the one to go for?
Also how common is it for a heat exchanger to die before 10 years? I know people who have had there boiler's for well over 15 - 20 years.
Thanks,
Sparky
