The big selling point of condensing boilers is that they are more efficient and will therefore save you money by reducing your gas consumption.
Has anyone, who has changed their boiler from non-condensing to condensing, done before and after comparisons of their gas consumption? If so what reduction in consumption did they achieve?
PS I have also posted this on another DIY site - there is no need to post two replies.
