For homes with above average hot water demands, look no further than FlowSmart.

FlowSmart at last enables even large households to enjoy the energy efficiency benefits of the combination boiler.

The combination boiler is the best and most energy efficient option for most homes with average hot water demands. They provide hot water only when there is a demand and operate without the need to keep a permanent store of hot water.

But due to limits on the combi boiler’s ability to supply large volumes of hot water to a number of outlets at the same time, the less efficient conventional boiler and hot water cylinder set-up is the usual choice for larger properties.

The Alpha FlowSmart system overcomes these issues and in fact, more than matches the hot water performance of a system boiler and 200 litre unvented cylinder, while using 25% less gas.
