Noritz NRC661-OD Water Heater

NRC661 OD Outdoor Tankless Water Heater

Noritz NRC661-OD Water Heater

The ENERGY STAR rated NRC661, 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 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.

Customer Feedback

What Customers Say About our Services Oved by number of customers throughout GTA!

We have been thinking about changing our 25 years old Ac for quite some time. Finally, last month we decided to change. We come to know about cosmopolitan through Lennox website.We got a very reasonable quote from cosmopolitan. Installation was done by the installer Dave. Very professional workmanship definitely deserves to be recommended.

If you need someone to repair your furnace or air conditioner call Cosmopolitan. We did and were very happy at the response and the cost a lot less than I had thought it might be. Greg gave me some good maintenance advice as well. We will call them from now on to do our pre season check and maintenance. It'll be well worth it.
