Potterton Promax 33kW Combi Boiler

Combi boilers are often the preferred choice of boiler, not only because they are designed to be compact and lightweight so that they can be easily wall-mounted in your kitchen cupboard, but also because they provide instant hot water when needed. This is because combi boilers are supplied with cold water directly from the mains, this water is then heated in the unit and distributed to your radiators and taps when needed.

The Promax 33kW is the most powerful in its range, however, many smaller homes do not have this high of a demand for central heating and hot water. In this case, you may be interested in the Promax 24kW or 28kW.
