Quick Product Details: KN26

Condensing, High Efficiency: 2,600,000 BTUs

The KN26 keeps the KN Series' tradition of excellence alive with its cast iron heat exchanger and full-modulation capabilities. Producing 2,600,000 BTUs within such a reduced footprint makes the KN26 a versatile condensing gas fired boiler sized to meet the most demanding operations within the commercial boiler industry.

From single boiler applications to multiple boiler master/member networks controlled by HeatNet 3.0 software, the KN26 is built for the long haul. Developed for maximum efficiency, the KN26's cast iron heat exchanger retains heat longer, allowing for shorter cycling and, most importantly, lower costs of operation.
