Noritz are a Canadian company who have been making water heaters for North America for more than 60 years. The NRC661 is their staple condensing natural gas tankless water heater, marketed by the company as “quality meets value”. Looking at the product’s specifications and price, it’s hard to argue the point: the NRC661 is available for considerably less than most condensing heaters, but it doesn’t look or perform like a budget option.
In fact, an energy factor of 93% is competitive with units that cost a lot more, while the maximum flow rate of 6.6 GPM should provide plenty of hot water for average houses and average-sized families.
The NRC661 is not particularly flashy, but it’s a no-nonsense unit that does what it sets out to do very well, and for a more-than-reasonable price. It even comes complete with its own diagnostic program, allowing it to identify and help you fix most of the common issues with natural gas tankless water heaters, should they occur.
For a quality condensing natural gas tankless water heater at a competitive price, Noritz are hard to beat; and the NRC661 is their flagship model.
