Accommodations at every turn.
In combination with custom-engineered, onboard boiler controls, KN Series boilers' patented cast iron sections accommodate a wider range of piping and water flow conditions more so than any other material or technology on the market.
All KN Series condensing boilers are capable of variable volume water flow up to 10:1 range and have low-pressure drops through the cast iron heat exchanger, and are also capable of delta T's of 20-100 with single pump system piping (reverse return) or primary/secondary piping. In direct comparison, competitive units typically have delta T's in the 20-40 range due to high-pressure drops and are not capable of single pump piping.
In addition to carrying a 21-year thermal shock warranty, KN Series boilers have no inlet water temperature limitations making them the perfect condensing boiler unit for one of the fastest growing segments in the hydronic heating market: snow melt and radiant heating.
