Noritz NRC661 Tankless Water Heater Delivers High Performance, Lower Installation Costs

Posted on by

The NRC661 (left) measures approximately 14 inches x 24 inches x 6 inches, allowing it to fit neatly into small spaces, such as a closet.

The ENERGY STAR®-rated NRC661 from Noritz America 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 eco-TOUGH™ Series of gas-fired residential tankless water heaters, the NRC661 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.

Half-inch gas connection: But the bigger news is that the market’s smallest condensing tankless water heater 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, as long as the water column pressure at the inlet of the unit is a minimum eight inches.

“We expect the NRC661 to challenge the conventional thinking that switching from tank to tankless water heating is unavoidably difficult and expensive,” says Noritz marketing manager Jason Fleming. “The new unit will not only carry a lower price point than our other condensing models, but its ability to use a half-inch gas connection will eliminate the need to up-size to a 3/4-inch run in replacement situations. That, in turn, should cut installation labor in half, resulting in a reduced installed cost to the homeowner.”

    For some, switching from tank to tankless water heating quite expensive, but having read about the benefits of this new innovation, I think that the switch is worth the risk.

    The ability to use an existing half-inch gas connection, rather than having to run a new three-quarter-inch gas-supply line, should make the tankless-for-tank switch more affordable — and the payback quicker — with the NRC661.

    Yes 1/12” connection is the game changer. I can mount this on an exterior wall and eliminate the old water heater closet and the carbon monoxide hazard.

    Tankless water heaters are an ideal way to save money and energy as they only heat the water as it is needed and not store a tankfull of hot water.
