Always Hot Tankless Commercial Water Heaters

Noritz makes the best tankless water heaters that save energy and water heating costs. Our energy efficient hot water heaters can be used for commercial or residential use, and are designed and manufactured for high efficiency (83-94 percent). An advanced electronic control system ensures an endless hot water supply without temperature fluctuations, providing on-demand hot water anytime. To compare a tankless water heater to a tank water heater: a tankless water heater only heats water when necessary, whereas a tank water heater constantly reheats the stored water to maintain the hot water temperature, even when hot water isn't being used.

The NC199, NCC199, NC250-ASME, NC380-ASME models have the capability of being installed together utilizing only the Quick-Connect cord. Two units (installed between 2-18 inches of each other) may be connected together by the Quick-Connect cord and controlled by a single digital remote thermostat, essentially doubling capacity. For heavy-duty industrial use, up to 24 units can be linked together with a system controller to supply a maximum of 316 gallons per minute, using the NC380-ASME model.

Features to Ensure a Long Life Capacity

Inside the heater, the copper heat exchanger is coated to prevent corrosion and deterioration, increasing the life of each heater. The internal piping of each commercial model is 25 percent thicker than residential models to extend the lifetime of the heater and prevent failure. Our burners use the latest in gas combustion technology, a result from over 50 years of developing and fine tuning tankless technology. This technology maximizes the output while maintaining high efficiency, which also results in low toxic emissions of NOx and CO.
