I currently have a 2 year old potterton suprima 50L and Heatrae-sadia mega flo. I've previously had (non-potterton) combi boilers and frankly am unimpressed with the potterton/mega-flo combination in comparison both for reliability and performance - (the potterton is currently on the fritz awaiting attention from an engineer.)
If I were to replace the above with a combi boiler, how do I decide what capacity/power output to choose? I have very little idea on what units of measurement are used to benchmark boilers (BTUs?) so would appreciate any guidance that is available.
