A ‘Combi’ boiler provides heat for your radiators and domestic hot water on demand. It works by taking cold water straight from the mains supply and heats it as you need it. This means there is no need for a separate hot water storage cylinder or cold water feed cistern. A System (or pressurized sealed system) boiler uses a sealed hot water storage cylinder which is usually installed in an airing cupboard. There is no need for an expansion tank in the roof as the combination of boiler and cylinder allows you to run mains pressure hot water from more than one outlet at the same time.
