There are three main types of boiler which can all be condensing: Combi boilers Heat only boilers System boilers
25/09/2018 · Condensing boilers are fitted with 2 internal heat exchangers to ensure that less heat is lost. Thanks to this, the boiler doesnt have to work as hard and uses less energy. Compared to a non-condensing unit, condensing boilers use less fuel and power while producing fewer CO2 emissions.
08/10/2019 · When a condensing boiler is operational, the two heat exchangers housed inside are able to recycle any excess heat produced and return it back to the system. No modern boilers (condensing boilers included) need a pilot light, as they use an electric spark when hot water is required. For further help, the diagram below offers a visual explanation of how a condensing boiler works
A condensing boiler captures some of the heat from these gases and uses it to heat water returning from your central heating system. It therefore requires less heat from the burner and is more efficient. All new modern boilers are condensing boilers.
