    Condensing combi boilers tend to be about 90% efficient this means 90% of the energy they use is converted into heat, or to put it another way, for every pound you spend, 90p goes directly on heating your home to put this in context, some older boilers are only around 55% efficient, which means you have to burn a lot.
