A combi boiler eliminates the need to store hot water so there is no hot water cylinder in the airing cupboard. It is both a high efficiency water heater and central heating boiler. The boiler runs ‘on demand’ and provides hot water to the heating system in the house or flat.
System boilers are often referred to as sealed system boilers because the system is filled to approximately 1 bar pressure and sealed.They are connected to a hot water storage cylinder, usually installed in an airing cupboard.
This type of boiler does not need an expansion tank in the roof. They are particularly good for homes with more than one bathroom because the combination of boiler and hot water cylinder can deliver hot water quickly to several outlets simultaneously.
