Courtesy: NavienThe Navien Condensing Gas Heating Boiler (NHB) is now available in four sizes: NHB-55, NHB-80, NHB-110, and NHB-150, with turndown ratios of 7:1, 10:1, 11:1, and 15:1, respectively. One key component to that efficiency is the newly developed dual Venturi gas delivery system. With a 95% AFUE rating, the NHB has Energy Star's most efficient designation. The NHB is designed for light commercial use and includes features like a timed hydronic supply water boost feature, an adjustable heat capacity, and an anti-cycle timer. It also has freeze protection, adjustable minimum burner time setting, and adjustable turndown ratio timing.
