The water vapour holds a significant amount of energy, known as latent heat. In a condensing boiler, the flue gases are cooled before being discharged, so the water vapour condenses (turns into liquid water). The latent heat released is used to preheat water returning to the boiler, and so condensing boilers are more energy-efficient than conventional ones. In order for this condensing process to work, the return water must be below a certain temperature. For this reason, and also that the flue gases are cooler and less buoyant, condensing boilers can’t always directly replace non-condensing boilers in existing buildings.’		[https://www.bsria.com/uk/product/oBKRqD/illustrated_guide_to_mechanical_building_services_3rd_edition_bg_312017_a15d25e1/ The Illustrated Guide to Mechanical Building Services, Third Edition (BG 31/2017)], by David Bleicher, published by BSRIA in 2017, states in relation to condensing boilers: ‘The flue gases (otherwise known as products of combustion) from a conventional boiler consist primarily of carbon dioxide (CO2) and water vapour, plus other gases such as oxides of nitrogen.
