NC380 Commercial Tankless Water Heater
by Noritz
A tankless water heater heats water on an as-needed basis, with no need for a tank to store all of the hot water, making tankless more efficient and less costly to operate than traditional storage tank water heaters. Add the ability to link up to 24 tankless water heaters and ASME certification, and you have a winning solution for your commercial hot water needs.

These tankless water heaters feature:
- Designed to provide enough hot water to meet the demands of hotels, resorts, or housing complexes with ASME certification and the ability to link multiple units in series
- 380,000 max BTU's for up to 13.2 GPM flow at a 45° F. temperature rise
- Includes digital remote control RC-7651M with 10' cord to turn the water heater on or off, set the temperature output, set a flow meter alarm, and lock the remote control operation
- User friendly on-board diagnostic computer system, combined with the included digital remote, provides ease of maintenance and temperature adjustment 100-150° F (In 5° F intervals), 160, 170, 185° F (14 options)
- Quick-connect (QC-1) cord allows the installer to connect 2 units for increased hot water demands
Connect up to 24 units under the same controller system to meet even greater hot water demands (requires optional SC-201 system controller)
- Direct electronic ignition eliminates standby pilot light and wasted energy
- Commercial grade HRS35 copper alloy heat exchanger and fully modulated burner work together to provide increased efficiency, stabilize temperature fluctuations, and boost performance of the flow rate for long life under heavy use
- Corrosion-free stainless steel casing protects the unit and allows for more efficient cleaning which reduces labor and maintenance costs
- Each unit takes up less than 3 square feet of space and can be installed inside or outside on walls or racks allowing them to fit nearly anywhere
- Use Category III 5" stainless steel venting
- Can be installed outdoors using optional Vent Cap #VC-132

Please note: For potential safety reasons, we do not recommend using PVC to vent gas tankless water heaters.
For the best results, we recommend using Category 3 stainless steel gas vent pipe for all gas tankless water heaters.
Frequently Asked Questions
Q. "What does the term "temperature rise" mean?"
A. Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.
Q. "How does a tankless heater provide hot water without a storage tank?"
A. Tankless water heaters heat on demand. The water is heated as it flows through the unit. Automated valves control water and gas flow so that your water comes out at the temperature you set it to.
Q. "What's the difference between a conventional flue and a direct vent?"
A. A conventional flue is what most people are familiar with. It typically consists of a double-wall flue pipe going from the top of the heater through the roof, venting outside. The fixture draws its combustion air from the space around it (utility room, garage, hallway, etc.). A direct-vent unit vents and draws its combustion air through a specially designed pipe from the outside via an adjacent wall.
Q. "What make a condensing tankless water heater different?"
A. Noritz condensing water heaters use a dual heat exchanger system to increase efficiency by using the residual heat from the exhaust temperature, which is captured by the first, corrosion-resistant stainless steel heat exchanger, to preheat incoming water before it runs through the main commercial grade copper heat exchanger. This reduces carbon dioxide emissions and increases efficiency. This also means vented exhaust is lower in temperature than other tankless water heater designs.
Q. "Can I use PVC to vent these tankless water heaters?"
A. The idea of using PVC venting instead of Category III stainless steel venting for condensing tankless water heaters (never recommended by the water heater manufacturer for non-condensing units) is that it will save money on venting since the exhaust temperatures are specified by the manufacturer as within the capabilities of PVC to handle safely. However, we never recommend PVC for venting. In the real world, gas water heaters are rarely maintained to their ideal, which eventually results in raised exhaust temperatures. These raised exhaust temperatures will pass beyond what PVC can safely handle and overheated PVC can release dangerous fumes and even collapse as it fails. For this reason, there is a higher incident of dangerous issues associated with PVC venting on gas tankless water heaters and we cannot, in good conscience, recommend PVC venting for gas water heaters.
Q. "How does the Water Heater Scale Inhibitor System prevent corrosion?"
A. It forms a thin protective layer on the inside of pipes and metal parts. This film or layer is microscopic in thickness and will not build up over time.
Q. "What are the best reasons to install a Scale Inhibitor System?"
A. A Scale Inhibitor System helps protect the system by reducing scale buildup and adding to the longevity and efficiency of the heater.
