The NRCR Residential Condensing Tankless Water Heater Series from Noritz uses a fully integrated pump to keep hot water close to even the farthest outlet in the home, minimizing the wait and, therefore, the waste of unused potable water down the drain. The NRCR heats water strictly on-demand, saving energy by eliminating the need to constantly reheat a full storage tank. The Auto Mode on the new NRCR quickly learns household water usage and automatically triggers recirculation-loop activation in line with that expected usage. The correct water temperature is delivered quickly when and where occupants need it the most.
