What is a combi boiler?

’Combi’ is short for combination boiler. This type of boiler heats water as you draw it from the tap and provides central heating. It doesn’t need a cold water feed and expansion tank or a hot water storage cylinder because the boiler is connected directly to the water mains, meaning it only heats water as and when it is needed. As you only have the combi boiler unit in this heating system, it can free up space for conversion, storage and living. Homes that need larger supplies of hot water are usually better suited to a system or open vent boiler with a hot water cylinder.
