Quick Product Details: KN2

Condensing, High Efficiency: 200,000 BTUs

The Energy Star-rated KN2 is ideally suited for residential and light commercial boiler applications, including new construction and retrofits. With a maximum output of 200,000 BTUs and capable of modulating down to a 40,000-BTU minimum, the compact footprint of the KN2 makes this cast iron condensing boiler the ideal choice to for hydronic space heat, radiant heat and snow melting applications.

And don't let its size fool you, the KN2 is built with the same quality, durability and levels of efficiency as larger KN Series units. Constructed with the signature KN Series cast iron heat exchanger, the KN2 offers unrivaled heat retention, resulting in lower operation costs.
