KN Product Family Overview

Innovation sized to meet the modern day requirements of low fuel utilization, high efficiency, longevity and the small footprint demands of today's condensing commercial boiler market. KN-Series Boilers are available from 200MBH to 2000MBH.

"I had a number of goals in mind when I designed the KN-Series boiler. One was to design a product that reflected modern requirements such as high efficiency, modulation, small footprint, etc. Another was to accomplish this in a manner that reduced the common problems associated with installation and the variability of the environment to which a boiler is subject over its lifetime."

The KN-Series boiler from HydroTherm is the first commercial boiler capable of realizing the high efficiencies of condensing applications using a durable cast-iron heat exchanger. KN-Series boilers combine the condition-tolerant, heat-retaining characteristics of cast iron with the energy savings of fully modulating, high-efficiency condensing performance
