Hi boiler experts
We've been recommended (well plumber thinks its a little overkill, but i'd rather that than underkill!) the following:
Vaillant Ecotec Plus 837 NG Cond Combi
Vaillant Eco std horiz flue duct 303933
Vaillant VRT360F wireless prog room stat
What do you think to that, and have you any ideas where I could get them for a good price?
