The new NRCP line of residential tankless water heaters from Noritz America combines the high efficiency of condensing technology with the comfort and savings of hot-water recirculation. A circulating pump inside the water heater keeps hot water close to the outlet, minimizing the wait and, therefore, the waste of unused potable water down the drain. Saving water, in this case, is doubly beneficial, because recirculation also avoids wasting the energy used to heat that water.
Using the integral digital display on the front of the water heater, homeowners can program the recirculation system to operate only when needed, with a precision down to the hour. An alternative, “auto” setting allows the system to quickly “learn” a household’s water-usage routines and automatically control the recirculation loop activation times, allowing for immediate hot water when it is needed most.
High efficiency for larger homes: Part of the Noritz ecoTOUGH™ Series of gas-fired residential tankless water heaters, the NRCP98-DV and the NRCP1112-DV have an Energy Factor of 0.95 for both natural gas and LP gas. These ratings are more than 10 points higher than that of a comparably sized, conventional tankless unit, and approximately 30 points higher than a standard, tank-type gas-fired water heater.
With a maximum input of 180,000 BTU per hour (BTU/hr), the NRCP98-DV has a maximum flow rate of 9.8 gallons per minute (gpm), making it generally suitable for homes with up to two-and-a-half baths.
The NRCP1112-DV, with a maximum input of 199,900 BTU/hr and a maximum flow rate of 11.1 gpm, is suitable for homes with up to three and a half baths.
Each unit delivers water from 100°F to 140°F, with a minimum flow rate for activation of 0.5 gpm.
