Noritz NRC661 Condensing Tankless Water Heater

Share With:

The ENERGY STAR-rated NRC661 makes choosing a high-efficiency, tankless water heater for the home more affordable than ever, especially when replacing a storage-tank-type unit. Featuring the same energy-saving condensing technology as the rest of the Noritz ecoTOUGH™ Series of gas-fired residential tankless water heaters, the NRC661 is the market’s smallest condensing tankless water heater. But it can deliver 6.6 gallons per minute, 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.
