As well as being far more economical, this means that there is no hot water cylinder, no tank in the loft (so less risk of freezing and flooding), and none of the connecting pipework.

Result: valuable extra space you can use for other purposes.

A condensing combi heats water directly from the cold mains whenever you turn on a hot water tap. This not only means that hot water is delivered on demand, but also at mains pressure, giving all the benefits of high-power showering without the need for a separate pump.

The average shower uses considerably less water than taking a bath, so the savings on hot water costs and water consumption can be very significant, particularly over a long period.
