When it comes to efficiency and innovation, one size doesn't always fit all.
Engineered to meet the demands of today's commercial condensing boiler market, KN Series by Advanced Thermal Hydronics are high efficiency condensing gas boilers built with the historically recognized reliability and strength of cast iron. As the first line of commercial boilers capable of realizing the full potential of cast iron, KN Series boilers take the heat-retention and durability of cast iron and couple it with the energy savings of fully modulating, highly efficient condensing boiler performance.
Capable of adapting to changing operating environments while generating 200,000 - 3,000,000 BTUs, KN Series boilers deliver environmentally friendly solutions for a wide range of boiler applications, all the while maintaining low fuel utilization and a small footprint. All KN Series models come equipped with HeatNet 3.0 boiler control software for precise system control through digital communication, and even have the option of remote monitoring through HeatNet Online.
Significant reductions in energy consumption, when coupled with low NOx and CO2 emissions, make KN Series' complete line of cast iron, condensing gas boilers an environmentally friendly, cost-effective option that will last for years to come.
