Get hot water for the entire house with 4 hot water uses running simultaneously.
Plus automatic scale detection.

The NC199 by Noritz is the upgraded version of the NC1991, and has an added feature of automatically detecting scale buildup on the heat exchanger. Instead of guessing when to flush your tankless heater, the NC199 will tell you.

More power: The NC199 series has more power than any other tankless water heater in the same class. It is ideal for mid-sized homes with up to 4 showers. Features include high elevation adjustment, safety lock-out and freeze protection.

Note: PVC cannot be used for venting.
