For low cost commercial and industrial heating.
The commercial range of Keston wall mounted gas condensing boilers covers outputs from 11 kW to 55 kW with single boiler units. As with all Keston boilers each has an extremely high efficiency performance of up to 98% (GCV).

Despite their powerful outputs each unit is designed for wall mounting.

Keston Boilers has launched two new commercial condensing gas boilers to further extend its existing range of ultra-high efficiency domestic and commercial boilers.

The Keston C90 (22kW to 90kW modulating. output) and Keston C110 (28kW to 110kW modulating output) are unique in concept and design and each have an exceptionally high efficiency at 98% (GCV).

The Keston C90 and C110 comprise high efficiency, single pass stainless steel heat exchangers with ultra-low emission burners. The boilers have been developed as an economic solution, in terms of price and space, to condensing technology with a choice of optional extras, which can be selected to suit the requirements of each individual installation.
