Strike while the iron is hot.

KN Series boilers are the first commercial boilers to achieve the high efficiency of condensed applications utilizing cast iron. Synonymous with durability and strength, cast iron is condition tolerant and heat retentive, which, when coupled with the energy savings of fully modulating, high-efficiency condensing boiler performance, makes KN Series cast iron boilers a force to be reckoned with.

Tried and true cast iron construction is at the core of every KN Series boiler.
