What is a Condensing Boiler?
Posted under: 
A condensing boiler works in the same way as a standard gas or oil boiler whether it’s a combination, system or conventional boiler the difference is that a condensing boiler is able to reclaim latent heat from the flue gases. The flue gases are waste gases produced by the combustion of fuel and is mainly made up of carbon dioxide and water vapour and contains significant levels of heat that would otherwise be lost as the gases are vented into the atmosphere.
A condensing boiler is capable of recovering this latent heat by redirecting the flue gases over a secondary heat exchanger before expelling the gases. The heat that is captured by the boiler from the flue gases is significant and will help reduce the boilers fuel consumption and in turn help reduce the household’s annual fuel bills and carbon emissions. As the heat is extracted from the flue gases the water vapour in the waste flue gases condenses and the water collects in the base of the flue, hence the name condensing boiler, this condensate will require draining away.
A condensing boiler is over 87% efficient helping to make significant saving in annual fuel bills as well as reducing the homes carbon footprint. In April 2005 government legislation made it law that all new boiler installations in the UK should be a high efficiency condensing boiler, this was brought into help the government reach it carbon reduction targets.
A wide range of Condensing Boilers are available to buy at BHL from leading manufacturers including Worcester, Vaillant, Baxi, Ideal, Biasi, Vokera, Glow-worm, and many others at competitive prices.
