The NRCP line of residential tankless water heaters combines the high efficiency of condensing technology with the comfort and savings of hot-water recirculation.  A circulating pump inside the unit keeps hot water close to the outlet, minimizing wait and waste. Homeowners can program the recirculation system to operate only when needed, or an alternative, “auto” setting allows the system to quickly “learn” a household’s water-usage routines and automatically control activation times. Both models have an Energy Factor of 0.95 for natural and LP gas — ratings more than 10 points higher than that of a comparably sized, conventional tankless unit.
