In a small property like mine (2 bed flat), what kind of differences in running costs would you see between a condensing and non-condensing combi boiler? Whilst I know condensing boilers are more efficient, is the extra expense worth it (does the extra efficiency worthwhile in a small property)?
PS. I am aware of the legalities (or non-legalities!) of installing non-condensing boilers, but I have a GSR friend who is happy to install a non-condensing combi if I so desire.
Thanks
