Potterton Promax Ultra 28kW Combi Boiler

Combi boilers are ideal for smaller homes with limited space. This is because they combine both the water heater and the central heating in one unit, removing the need for any additional hot or cold water tanks as you would need with a regular or system boiler.

Combi boilers are also perfect for homes that need instant hot water, this is because the boiler is supplied with cold water directly from the mains, and then heating within the unit and then distributed to your radiators or taps when needed.

With an output of 28kW, this combi boiler can heat a home with up to 15 radiators and a bathroom. If you feel that this boiler does not meet the demands of your home, Potterton has designed the Promax Ultra 33kW and 40kW, which could be better suited for your home.
