Noritz NR71 (N-0631S) Tankless Water Heater

Noritz NR71 (N-0631S)

Providing 6.3 gallons of hot water per minute, the Noritz NR71 (N-0631S) Series of tankless water heaters is the best choice for homes with one to three showers. Similar to other Noritz models, the NR71 is built with state-of-the-art combustion technology, which means an endless supply of hot water with lower energy costs. In fact, the NR71, like most Noritz tankless water heaters, comes with the government Energy Star label.

There are two different models in the NR71 series, the NR71-SV and the NR71-OD. The SV model can be installed inside or outside the home, and has an Energy Factor of 0.83 in both the natural gas and propane versions (the higher the Energy Factor, the more energy efficient the water heater is). The NR71-OD model is for outdoor installation only, and has an Energy Factor of 0.82 in the natural gas version and 0.83 in the propane version. Both models come with the standard Noritz warranty – 12 years, 5 years parts, and 1 year labor. Both also have twelve temperature settings, ranging from 100 to 160 degrees Fahrenheit. Furthermore, both models will save you money not only on your energy bill, but also on your taxes: installing a Noritz NR71 tankless water heater entitles the owner to (up to) $1,500 in tax credits for 2009 and 2010.

During the summer, when temperatures outside are 70 degrees Fahrenheit or higher, you can expect your NR71 to provide plenty of hot water for three simultaneous showers. During the winter months, when temperatures outside are 45 degrees or lower, expect plenty of hot water for two simultaneous showers.

This nearly endless supply of hot water is made possible by the NR71's high performance single flame burner, its resin-coated PC board (increases durability and insulates the unit from the elements), and the automatic air regulator (maximizes burner efficiency). If you're considering purchasing a tankless hot water heater, the NR71 is an excellent value for average-sized homes.
