Whats so good about condensing boilers?
As your installer will confirm, condensing boilers can be easily fitted to most new and old heating systems. But what makes them better than older, non-condensing boilers is their efficiency: they waste far less energy. Put another way, while poor old non-condensing boilers convert just 60% of their fuel into heat, the efficiency rate of modern A-rated condensing boilers is at least 90%. An A-rated condensing boiler will also use a third less fuel than an older boiler to provide the same amount of heat – potentially cutting heating bills and CO 2 emissions by a third too. All of which makes condensing boilers the most efficient boilers on the market.
