K2
High-Efficiency Gas Boiler
Stainless Steel Heat Exchanger
Contractors told us exactly what they wanted.
A value-priced, high-efficiency condensing boiler that is simple enough to install quickly AND offers valuable extras not found on competitive models. U.S. Boiler Company has delivered. The K2 offers a comprehensive feature list, and unequaled ease of setup, maintenance, and operation in a package that costs far less than you’d expect for the impressive value that’s built-in. Best of all, it’s built and tested with pride in Lancaster, Pennsylvania by the U.S. Boiler Company.
Furthermore, with the advanced Sage2.3™ Control System, the K2 condensing boiler now offers 10:1 turndown and impressive gains in efficiency. The K2 is 95% AFUE for all sizes!
The K2 condensing boiler’s simplified design includes a hinged inner door that isolates electronics and controls from combustion and waterside components, making for fast, clutter-free service access. Venting the K2 is simple as well, regardless of whether one-pipe, two-pipe, horizontal, or vertical configurations are needed.
