Condensing Gas Boiler Efficiency

Condensing Gas Boiler Efficiency


PEOPLE Boiler Efficiency - energyCondensing boilers have the potential to reduce gas consumption for space heating by as much as 15%, providing they are carefully selected, monitored, controlled and maintained. 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 the water vapour in the waste gases to liquid and recovering its latent heat2. Condensing boilers also have high efficiency …condensing boiler - Search condensing boilerCondensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is
