PEOPLE Boiler Efficiency - energy.gov.au

2018-6-14 · A typical condensing boiler has a thermal efficiency of 92-95%, in comparison to non-condensing boilers which typically have efficiencies of around 85%. These higher efficiencies are achieved by using the waste heat in the flue gases to preheat the water entering the boiler. Additional heat is extracted by condensing
