Designed to meet diverse commercial needs, the Rheem IKONIC Commercial Tankless Gas Water Heater provides flexibility with multiple sizing and design options. IKONIC Commercial is available as a single unit, complete Factory Pre-Built/programmed rack systems (RTRS), or as a Modular (DIY) build-on-site solution.

The new Rheem IKONIC Commercial offers a single unit that caters to both natural gas and liquid propane commercial applications with the inclusion of a fuel conversion kit. Plus, it will seamlessly transition between indoor and outdoor applications using an optional outdoor conversion kit.
