Boiler Efficiency — What Gross and Net Efficiency Mean

Using the same combustion gas analysers, most high efficiency boilers are about 90% gross efficient (10% of your money is wasted). Changing from a reasonable, old, room-sealed boiler to a new high efficiency boiler will save you about 10% - 15% of the money you spend on gas. Figures claiming savings of 30% or more seem not be be physics but magic.
