  • Noritz – NRC661 OD Condensing Tankless Water Heater

    The ENERGY STAR rated NRC661 OD, Noritz's newest efficient condensing model with a half inch gas line. Featuring the same energy‐saving condensing technology as the rest of the Noritz eco‐TOUGH™ Series of gas‐fired residential tankless water heaters, the NRC661 OD has an Energy Factor of 0.91 for natural gas and 0.93 for LP. These ratings are nearly 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 120,000 BTU per hour (BTUh), using a half‐inch gas line up to 120 feet in length. A new, more accurate interpretation of the National Fuel Gas Code permits the use of the smaller‐diameter gas piping for inputs up to 174,000 BTUh, as long as the water column pressure at the inlet of the unit is a minimum eight inches.
