As commercial facilities push for higher efficiency, redundancy, and lower lifetime operating costs, Noritz America is making a clear statement about where it sees the future of hot water systems. At the 2026 AHR Expo in Las Vegas (February 2–4), the company will debut a new commercial-focused marketing initiative dubbed “Commercial One,” centered on its flagship NCC199 CDV Pro tankless water heater.

The campaign will be showcased at Booth C4929 in the Central Hall of the Las Vegas Convention Center and reflects Noritz’s broader strategy: repositioning tankless systems not as niche alternatives, but as purpose-built infrastructure for high-demand commercial and industrial environments.

A “True Commercial” Take on Tankless Water Heating

At the heart of Commercial One is the NCC199 CDV Pro, a unit Noritz positions as a “True Commercial” tankless water heater—engineered specifically for sustained, high-load applications rather than light commercial crossover use.

The specs are designed to signal seriousness. The NCC199 delivers a maximum input of 199,900 BTU per hour, supports flow rates up to 11.1 gallons per minute, and achieves an Energy Factor of 0.98 UEF. It’s CSA-approved for common venting of up to six units, simplifying large installations while maintaining compliance.

Durability is a core selling point. The system uses dual corrosion-resistant stainless steel heat exchangers, a design choice aimed at extending lifespan under heavy use. Noritz backs that confidence with an industry-leading 10-year warranty on the heat exchangers, a notable differentiator in a market where downtime can be as costly as energy inefficiency.

Scaling Without Compromise

While the NCC199’s individual performance is important, Commercial One is less about single units and more about system-level thinking. Noritz is emphasizing how multiple NCC199 units can be linked to create scalable, redundant systems that deliver continuous hot water—even during maintenance.

That systems approach is enabled in part through Facilities Resource Group (FRG), a Noritz Group company based in Grand Rapids, Michigan. FRG designs, builds, installs, and services commercial multi-unit rack systems anchored by the NCC199, with a focus on businesses where hot water interruptions simply aren’t an option.

Fast-food and casual dining chains are a prime example. FRG’s client roster includes Texas Roadhouse, Panera Bread, Love’s, and Chili’s, operations where peak demand, tight margins, and uptime expectations collide.

“Our commercial systems are designed with redundancy firmly in mind,” said Ben Wirick, vice president at FRG. By linking multiple Noritz tankless units, he explained, individual heaters can be serviced without interrupting hot water supply—a critical capability for 24/7 or high-volume operations.

Intelligent Load Sharing at Commercial Scale

In multi-unit configurations, Noritz systems are designed to communicate and balance workloads automatically. Rather than overworking a single heater, the system distributes demand evenly, helping extend equipment life and maintain consistent output.

According to FRG, isolation valves and system controllers ensure proper operation and even wear across units, offering facility owners operational predictability and fewer surprise failures. At the upper end, linked Noritz systems can deliver up to 9.1 million BTU per hour and 316 gallons per minute, pushing tankless technology into territory once dominated by large centralized boilers and storage tanks.

This approach aligns with a broader industry shift toward modular infrastructure—systems that scale incrementally, fail gracefully, and adapt to changing demand rather than relying on oversized, monolithic equipment.

Rack Systems Designed for Real-World Installations

Noritz’s Commercial One message also highlights the physical infrastructure that supports these systems. The company offers multiple rack and manifold configurations tailored to different commercial environments:

• CR61 Rack: A pre-fabricated, multi-unit racking system designed for flat rooftops or mechanical rooms in large commercial facilities.

• Commercial Manifold and Rack Kits: Wall-hung CMK Manifold Kits and floor-mounted CRK Rack Kits, pre-assembled in the U.S. and shipped flat-packed to simplify transport and on-site assembly.

• Total Tankless Solutions (TTS) Synergy Series: A highly customizable platform that combines up to six NCC199 units in a single rack with centralized connection points for water, gas, power, venting, condensate, and circulation.

The TTS approach is particularly aimed at accelerating replacements of large centralized domestic water-heating systems. With integrated storage tank options and fewer connection points, Noritz says the system can significantly reduce on-site labor and downtime—key concerns for retrofit-heavy sectors like hospitality, healthcare, and education.

Positioning for a Broader Commercial Push

For Noritz, Commercial One is as much about perception as product. Tankless technology has long been associated with residential efficiency and point-of-use applications. This campaign reframes it as a robust, enterprise-grade solution capable of serving restaurants, schools, hospitals, hotels, apartments, and even agricultural and industrial operations.

“Our products are engineered and built to remove the worry over having enough hot water,” said Jason Fleming, Executive Vice President and General Manager at Noritz. The message is clear: reliability and scalability are no longer trade-offs for efficiency.

As commercial operators increasingly demand energy efficiency without sacrificing resilience, Noritz’s system-centric approach—and its emphasis on redundancy and modular growth—positions the company squarely in the conversation about next-generation commercial water heating.
