Noritz is proud to introduce our most efficient tankless heaters, the next generation in tankless technology - Noritz NRC111-DV-NG Natural Gas Condensing Tankless Water Heaters. This innovation utilizes a dual heat exchanger, a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the heater's efficiency level to over 93%! Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the heater for easy installation.
It's the coolest and greenest tankless water heater available today! This is the highest performing condensing unit on the market today. Some other brand(s) may have a bit higher efficiency rating, but there is a fine balance between the efficiency level and flow rate performance. At Noritz we strive to maximize efficiency levels without sacrifing the hot water output, temperature fluctuations, and water pressure. Comfort and safety is something we do not compromise on.

Noritz prides itself on being the best tankless water heater manufacturer to supply all of your commercial hot water needs. To determine which tankless water heater model is right for you, you first need to identify your peak hot water usage. The estimation chart shown can guide you to find the right sized commercial tankless hot water heater for your commercial building.
Each showerhead illustrated below is about 2 GPM, which is roughly what a standard showerhead, bathroom sink, dishwasher, and washing machine would use. To meet all commercial hot water heater needs, these tankless hot water heaters can be linked together to provide on-demand hot water for every application. The number of showerheads next to each series shows the heater’s capacity of providing hot water simultaneously.
PLEASE NOTE: The chart is for ESTIMATION ONLY. Before installation, have a registered plumber size the application according to Noritz Specification Sheets to ensure the model can accommodate your hot water needs.
