What is a Combination Boiler?

A combination (or combi boiler) is a compact and highly efficient unit giving all the heating and hot water you need, with significant savings on running and installation costs.

Unlike a conventional heating and hot water system,a combination boiler system does not store hot water. It heats water directly from the cold mains - as you use it. There's no hot water cylinder, no tank in the loft (and so less risk of freezing and flooding), and none of the connecting pipework. So you not only save space, but also considerably reduce hot water costs- which can account for up to 60% of a domestic fuel bill.

A combination boiler also supplies hot water at mains pressure, giving you exhilarating power showering without the need for a pump. And as, on average, a shower uses considerably less water than a typical bath, the savings on hot water costs and water consumption can be significant.

Manufacturing boilers which can deliver 4 gallons every minute and are able to supply 2 or even 3 hot taps simultaneously Worcester Bosch is one of our most popular manufacturers.
