Im looking to change my old boiler to a new more efficent condencer boiler.. i have looked a Bord Gais and the prices from them runs in to many thousands.
Im looking to buy my boiler myself and hire a plumber to fit and install new heating zones (need to do this for SEI Grant)
So im looking for advice from anyone who changed, did you notice a big difference in your bills? If you sourced your own boiler where did you buy? Also looking would you recommend anyone to fit and rezone my system?
