KD Navien has developed its industry leading reputation in the United States and Canada as a tankless water heater and combi-boiler company. With deep experience in the manufacturing of boilers and the largest single boiler manufacturing facility in the world, the company will expand its product line in the U.S. and Canada in the fourth quarter when it begins selling the NHB (Navien Heating Boiler) series, in four sizes, for residential and light commercial use: NHB-55, NHB-80, NHB 110 and NHB-150 with turn-down-ratios respectively of 7:1, 10:1, 11:1, and 15:1. The noteworthy 15:1 TDR in the NHB-150 is achieved with Navien’s newly developed dual Venturi gas delivery system.
