Condensing Boilers Evaluation Retrofit and New

Condensing boilers achieve higher efficiencies by condensing water vapor contained in flue gases. When natural gas is combusted in a boiler, approximately 90% of the energy contained in the fuel is converted into sensible heat (heat that causes a change in temperature) and approximately 10% is converted into latent heat (heat

Condensing vs. Non-Condensing Boilers (2021) GreenMatch

The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. Their level of efficiency is achieved by using waste heat in flue gas to preheat the cold water entering the boiler, capturing more heat from the outside rather than the inside of a room.

The flue is essentially the pipe that transports these gases out of the boiler. As the gases can be potentially harmful, it's important that the flue is situated in such a way that the waste gases do not re-enter the property. Similarly, the placement of a boiler flue should ensure that waste gases are not directed towards neighbouring
