Range Guide

Keston BOILERS
The commercial range of Keston wall mounted gas condensing boilers covers outputs from 38 kW
(Keston 130) to 100 kW (Keston 340) with single boiler units. As with all Keston Boilers each has
an extremely high efficiency performance of 98% (GCV).
Despite their powerful outputs each unit is designed for wall mounting though floor standing
installations can be accommodated for the Keston 260 and Keston 340 using an optional floor
standing frame.
Keston Boilers offer complete and cost effective solutions to commercial and industrial heating and
in all installations can offer the highest quality systems. These are very often at much lower costs
than a single commercial boiler of equivalent output.
