Unlike a conventional heating and hot water system, a Combi system does not store domestic hot water. It heats water directly from the cold mains, as you use it. There’s no requirement for a hot water cylinder, no tank in the loft (and so less risk of freezing and flooding) and none of the connecting pipe work. So you not only save space, but also reduce hot water costs – which can account for up to 60% of a typical domestic fuel bill. A Combi Boiler also supplies hot water at mains pressure, giving you exhilarating power showering, without the need for a pump.
