KN Series

KN-Series boilers represent revolutionary engineering.

The world’s first boiler to pair condensing performance with cast iron’s durability. No other boiler can match it point for point when it comes to set-up, maintenance, and long-lasting performance. Not one.

All KN-Series cast iron sections are manufactured in the USA for durability and longevity by people with generations of foundry and manufacturing expertise in Boyertown, PA. All castings have precision machined ports for water tight joint seals and are rated at 100psi of working pressure. KN-Series boilers retain valuable latent heat energy for maximum efficiencies.

Long life and dependability.

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 3000MBH.
