New Noritz NRC661 Condensing Tankless Water Heater Delivers High Performance and Lower Installation CostsSubscribe to RSS feed
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.”
Major enhancements: The new NRC661 also offers three other key features not previously available:
BUILT-IN DISPLAY WINDOW: The NRC661 is the first Noritz unit to offer an integral display window on the front of the unit to permit basic troubleshooting without the need for a remote device. Located at the lower-right of the front panel, the small window displays the set-point temperature, maintenance monitors and indicators for common problems.
LOW MININUM INPUT: The NCR661 offers a minimum gas input of only 15,000 BTUh. This is perfect for warm weather climates to avoid overheating incoming water that is already warm.
ACCESSIBLE TECHNICAL DATA SHEET: To assist both installers and service technicians, Noritz has located the NRC661’s Technical Data Sheet, showing all the error codes and their respective solutions, right inside the unit’s front cover. “The trades person no longer needs to call Noritz,” comments Fleming. “The troubleshooting solutions are right at his fingertips.”
Installation flexibility: Designed for two-bath residences in the warm-weather climates of the South and West, the NRC661 offers temperature settings from 100°F to 140°F in both indoor and outdoor units. For the indoor direct-vent model, condensing technology permits venting with installer-friendly, three-inch PVC or CPVC pipe, which is less expensive than the Category III Stainless Steel venting required by conventional tankless units. The zero-clearance plastic piping enables longer vent runs – up to 62 linear feet – and therefore greater installation flexibility at a lower cost. (See adjacent box.)
Like other models in the ecoTOUGH Series, the NRC661 protects the environment by heating water strictly on demand, while offering a longer product life cycle than storage tank-type models. Carrying a 12-year warranty on the heat exchanger and five years on all parts, the NRC661 promises lower emissions, reduced electrical consumption, smaller amounts of potentially hazardous construction materials, and easier recyclability of those materials and components once the product is removed from service.
The NRC661 is equipped with the advanced technology of the fully modulating, low-NOx Eco-Burner™ with a nitrogen-oxide emissions level of 20 parts per million that fully complies with the new South Coast Air Quality Management District regulations. The Eco-Burner delivers superior temperature control, eliminating the need for a buffer tank to stabilize the temperature. This, in turn, removes another potential source of standby heat loss, thus maintaining system efficiency.
