Boiler Efficiency: Which Boilers Are Most Energy Efficient?
Condensing boilers are the most energy efficient, typically being 25% more efficient than non-condensing models. If you still have a old-style non-condensing boiler, then replacing it with a new condensing boiler could save you £45 to £300 a year (Energy Savings Trust, 2021). All modern boilers that you can buy are condensing boilers and have
Read MoreDecrees to Increase Energy Efficiency of Boilers
Two decrees were revised in 1998 to increase energy efficiency, both becoming effective in 2000. One imposes minimal thermal efficiency standards for boilers in service when their power production is between 400 kWh and 50 MWh. The second requires periodic inspection of boilers with a capacity greater than 1MW.
