Benefits of Our 36kW Combi Boilers

Bithermic Heat Exchanger

Our combi boilers are all fitted with our innovative bithermic heat exchanger, invented and pioneered by us in 1996. Not only does the part come with a minimum 7-year warranty, but its simple construction and reliance on fewer moving parts reduces the likelihood of breakdowns, delivering a long-lasting combi boiler at 36kW.

 

Energy Efficiency

Our Xclusive 36 and Xtreme 36 combi boilers have achieved A-rated energy efficiency across both seasonal heating and water heating. The innovative heat exchanger provides 93% efficiency for central heating and 87% efficiency for hot water (93% on the Xtreme model).

 

Compact Size and Flexible Placement

We know how important boiler size is, so we provide compact options across our range. Our Xtreme 36 and Xclusive 36 units are 826mm x 450mm x 277mm (minus jig), with up to 10m flueing distance (or 50m with our twin flueing option). 

 

Perfect for Larger Homes

This 36kW combi boiler is ideal for larger properties that have at least two bathrooms and between 15 and 25 radiators.
