[Condensing technology]

Condensing boilers are already immensely popular in mainland Europe (accounting for 80% of some markets) and Buderus have been at the forefront of developing condensing heating technology in the European market for decades.

Using an old or inefficient conventional boiler can mean that up to 50% of the heat that is generated through the combustion process is lost through the flue in the form of water vapour. This heat is completely lost to the outside environment, yet you still have to pay for the gas that generated it. In economic terms this means that every £1 spent on gas to heat your home, as much as 50 pence worth can be lost through the flue.

A condensing boiler works by cooling down the hot flue gasses before they escape through the flue. As the hot water vapour cools, it turns back into a liquid (condensate) and releases heat back into the heating system via the heat exchanger. The flue gasses that do escape from a condensing boiler are much cooler because the heat has been put back into the system, and used to warm your home. In simple terms, this is why a condensing boiler can operate at efficiency levels of over 90%, and why less fuel is needed to achieve a greater level of heating comfort.
