Navien has announced the launch of the NDF600 Condensing 2-Stage Gas Furnace, a new gas furnace engineered to deliver exceptional comfort, installation flexibility, and dependable performance for contractors and homeowners alike. Designed with both performance and serviceability in mind, the NDF600 combines 96% AFUE efficiency, two-stage operation, and a variable-speed ECM blower motor to provide consistent indoor comfort while helping reduce energy consumption. The two-stage heating operation automatically adjusts output to match demand, minimizing temperature swings and delivering quieter operation than conventional single-stage furnaces.
