Offering efficiency levels of over 85 percent condensing boilers are by some distance the most energy efficient type of central heating boilers currently available in the UK. In comparison a new standard boiler will be at most 78 percent efficient with older systems being as little as 60 percent efficient.
A condensing boiler makes better use of the heat that it generates from burning fuels such as gas or oil. They work by recovering the heat that would normally be wasted by conventional boiler systems. In a conventional boiler some heat is lost because the boiler releases very hot waste gases from its flue. Instead of wasting this energy a condensing boiler uses some of the heat from these waste gases to heat water returning from your central heating system, so it requires less heat from the burner. This makes your condensing boiler more efficient. Continue reading ‘Condensing Boilers – A Quick Guide’ »
