Hi there - 5 years ago I replaced a leaking Potterton boiler with a Keston C25 (it was reccomended due to the fluing being awkward as boiler is downstairs in a split level flat).
The Keston has been nothing but trouble - at first it chuffed, so was forced to have a bypass installed, and then it kept getting hydrogen in the system (radiators constantly filling with gas), so then it was converted to sealed system (that was a waste of money - it made no difference). Now its conked out and it looks like the heat exchanger is gone.
So I have had some quotes for replacing the whole lot with a Combi system - and everyone seems to be recomending Vaillant (which I read good things about here).
I seem to get pointed to either an Ecotec 831 or an 824 (not sure which one I need). Its a 2 bedroom flat with 6 radiators. I have 1 bathroom with a shower and a bath.
Some quotes insist on a power flush other says that given it was flushed 5 years ago it should be ok.
They all say the gas to the boiler needs upgrading to 25mm (which is probably under a floor board somewhere as it goes into the building at 25). 1 quote says I should add £30/m for copper pipe for that upgrade (which sounds steep - but they said copper is expensive).
As I feel I was totally ripped off the last couple of times, I'm quite "gun shy" of the whole operation and mad as hell that I even have to get a new system only 5 years later.
Can anyone give any advice/tips? Am I on the right track with this?
