The NR83-DVC  is the latest addition to the Noritz collection of whole-home, residential tankless water heaters. The NR83-DVC will allow professional plumbing installers to make a strong eco-friendly statement to homeowners interested in shrinking not only their carbon footprint but their fuel bills as well.

Just like all tankless water heaters, the new concentric-vented NR83-DVC saves energy while it protects the environment simply heating water on demand. The NR83-DVC offers a longer product life span than standard tank water heaters. The NR83-DVX also touts lower emissions, reduced electrical consumption, smaller amounts of potentially hazardous construction materials. To top it off, the NR83-DVC boasts easier recyclability of those materials and component as well.

The Noritz NR83-DVC is the greenest tankless water eater to hit the market. Featuring an eco-friendly design, the NR83-DVC boasts the following green improvements over the previous generation of tankless water heaters:

• Reduced amounts of hexad chrome in the coating of the exterior and the burner case
• Reduced amounts of lead in the water-flow servomotor, the lightning protector and the circuit board
• Reduced amount of cadmium in the inlet/outlet bracket
• Reduced consumption of standby electricity

Perhaps most impressive is that Noritz has attached component specific alpha codes within the NR83-DVC to aid in identifying recyclable parts at the end of the water heater's life cycle


"Noritz is committed to investing in technologies and products that will reduce the burdens on our environment, including atmospheric pollution," says Bob Hitchner, Vice President of Business Development & Marketing for the Noritz America Corporation.


"We are also committed to providing our distributors and their contractor customers with the most complete lineup of whole-house tankless products on the market. The NR83-DVC allows us to achieve both goals, giving professional contractors even more options to meet the needs of their customers."


Product specifications
With inputs ranging from 18,000 BTU per hour to 180,000 BTU/H and flow rates from 0.5 gallons per minute to 8.3 GPM, the NR83-DVC is designed specifically for one-bathroom homes in the Northeast, the Midwest and Canada, as well as two-bath residences in the Southeast and Southwest. At a 45°F rise in temperature, the unit will operate at a flow rate of 6.7 GPM, delivering water temperatures from 100°F to 140°F.


"The intermediate size of this unit enables the contractor to offer smaller homes a more affordable tankless solution, while meeting all of a household's daily hot-water needs," Hitchner explains.

Measuring a compact 23.6 inches x 13.8 inches x 9.4 inches, the 49-pound water heater offers these important features:

• Low NOx, Eco-Burner™: The NR83-DVC is the first model in the Noritz residential line to use a new, high-efficiency low-NOx Eco-Burner that reduces emissions. 
• Commercial-grade heat exchanger: The NR83-DVC is the only tankless water heater in its category with a commercial-grade heat exchanger that features a pipe diameter 15% larger and 25% thicker than a standard residential unit. Built for higher performance as well as longer life, the NR83-DVC heat exchanger also has a larger "fixed" bypass to boost its maximum flow rate from 7.1 GPM to an industry-leading 8.3 GPM, a 17% gain in capacity over the Noritz NR71. 
• Adjustable concentric venting: The 3-inch/5-inch, pipe-within-a-pipe construction of the Category III Stainless Steel Venting Kit reduces installation time over a two-pipe system by offering zero clearance to combustibles and by requiring only one wall penetration, not two. Also, Noritz venting materials are fully adjustable to the length of the vent run and the number of elbows. This flexibility spares the installer from the time-consuming chore of custom-cutting and assembling lengths of pipe and fittings to build a system. Vent runs can extend up to 38 feet with no elbows; to 21 feet with three elbows. This kit can also be used with the Noritz NR98-DVC model, designed for larger residential applications, thus reducing venting-material inventories a contractor needs to fully serve the whole-home tankless water heater segment. 
• Dipswitch adjustments: The NR83-DVC further simplifies the installation job by eliminating all wire connectors. Adjustments for vent length, high-elevation settings and default temperature settings can be made on a dipswitch bank that is readily accessible near the top of the circuit board inside the unit. The NR83-DVC accommodates four different high-elevation settings: standard, 2,000 feet, 4,000 feet and 6,000 feet. 
• Programmable remote controller: Displaying temperatures in both Fahrenheit and Celsius, this new controller can be programmed to remind the homeowner to call for servicing at six-, 12- or 24-month intervals, but without disrupting normal operations.
