The Noritz NC380-SV-ASME-NG 13.2 GPM 380,000 BTU Commercial Natural Gas Single Vent ASME Tankless Water Heater is engineered to provide continuous, high-capacity hot water for demanding commercial applications including restaurants, hotels, apartment buildings, healthcare facilities, schools, and other large commercial properties. Unlike traditional storage tank water heaters that store a limited amount of heated water, the NC380-SV-ASME-NG heats water only as it is needed, providing an endless supply of hot water while eliminating standby energy loss.
Featuring an ASME-certified heat exchanger for commercial installations, the NC380-SV-ASME-NG delivers up to 380,000 BTU of natural gas heating power with a maximum flow rate of 13.2 gallons per minute. Its fully modulating burner automatically adjusts between 22,500 and 380,000 BTU to match hot water demand, helping improve efficiency while maintaining consistent outlet temperatures. The compact wall-mounted design helps maximize mechanical room space and supports both individual and multi-unit commercial installations.
Product Features:
- 380,000 BTU Maximum Input: Provides exceptional natural gas heating capacity for high-demand commercial applications.
- Up to 13.2 GPM Flow Rate: Delivers continuous hot water to multiple fixtures simultaneously depending on incoming water temperature and required temperature rise.
- ASME Certified Heat Exchanger: Built to meet ASME Section IV requirements for commercial water heating installations.
- Commercial Non-Condensing Design: Heavy-duty non-condensing construction provides dependable commercial performance.
- Single Vent Installation: Designed for indoor installations using approved 5-inch Category III stainless steel venting or outdoor installation with an optional Noritz vent cap.
- Fully Modulating Burner: Automatically adjusts firing rate from approximately 22,500 BTU to 380,000 BTU to maintain consistent water temperatures while reducing unnecessary fuel consumption.
- Commercial Copper Heat Exchanger: Heavy-duty K-type copper heat exchanger is engineered for long service life in demanding commercial environments.
- Multi-System Capability: Connect up to 24 compatible Noritz units using optional system controllers to provide over 9 million BTU/hr of commercial hot water capacity.
- Wide Temperature Range: Adjustable outlet temperatures from 100°F to 180°F support a wide variety of commercial applications.
- Recirculation Compatible: Compatible with commercial recirculation systems for faster hot water delivery.
- Built-In Safety Features: Includes freeze protection, flame monitoring, overheat prevention, fan rotation monitoring, lightning protection, and advanced self-diagnostics.
What Is an Isolation Valve Kit?
An isolation valve kit is strongly recommended for commercial tankless water heater installations. Isolation valves allow the water heater to be disconnected from the plumbing system for maintenance, flushing, descaling, and servicing without shutting off water to the rest of the building.
Regular descaling is especially important in commercial applications where higher operating hours and hard water conditions can accelerate mineral buildup inside the heat exchanger. Installing isolation valves helps simplify maintenance and maximize long-term performance.
Short vs. Long Isolation Valve Kit
For the Noritz NC380-SV-ASME-NG, only one isolation valve kit is required depending on your installation layout.
- IK-WV-200-5-TH-S Short Isolation Valve Kit: Designed for installations with limited clearance.
- IK-WV-200-5-TH-L Long Isolation Valve Kit: Recommended where additional service space is available for easier maintenance.
Both kits include durable 3/4-inch threaded isolation valves along with a lead-free pressure relief valve.
Understanding Tankless Water Heater Sizing
Commercial tankless water heaters are selected using flow rate (GPM) and temperature rise rather than storage capacity. The colder the incoming water, the more heating capacity is required and the lower the available flow rate.
For example, if incoming groundwater is 50°F and the desired outlet temperature is 120°F, the required temperature rise is:
120°F − 50°F = 70°F Temperature Rise
Consult the Noritz flow rate chart to determine the expected hot water output at your required temperature rise and ensure the water heater is properly sized for your building's simultaneous demand.
Warranty
The NC380-SV-ASME-NG includes a Noritz commercial limited warranty featuring a 5-year heat exchanger warranty, 5-year parts warranty, and 1-year labor warranty for qualifying commercial installations. Always verify natural gas supply, venting requirements, water quality, local plumbing codes, gas sizing, and all required accessories before installation.
Heavy-Duty Commercial Tankless Water Heating Performance
The Noritz NC380-SV-ASME-NG is a high-capacity commercial tankless water heater engineered to meet the demanding hot water requirements of large-scale commercial facilities.
