Commercial Tankless Features & Benefits

SYSTEM REDUNDANCY icon

SYSTEM REDUNDANCYThe factory-installed manifold controller on select models allows up to 20 units to be daisy-chained together via the included manifold control cable. So if one unit goes down, the business can stay up and running.

SERVICE NOTIFICATION SETTING icon

SERVICE NOTIFICATION SETTINGProper service and maintenance can lead to a longer life for the water heater. This maintenance alert feature is set by the contractor upon installation at the owner's request. After 500 hours of use, the owner is alerted via a flashing warning code that it is time to service the unit.

COMMERCIAL READYRheem Commercial Tankless Water Heaters are made for hardworking environments, with high-temp chip factory-installed. And manifold control models make creating a multi-unit setup plug-and-play.

OVERHEAT DETECTION OVERRIDE icon

OVERHEAT DETECTION OVERRIDEIn the event the system overheats, Rheem's exclusive Overheat Film Wrap will immediately shut the unit down to prevent damage.

BUILT-IN CONDENSATE NEUTRALIZER icon

BUILT-IN CONDENSATE NEUTRALIZERThe acidic water that is a byproduct of combustion can corrode and damage pipes, but the built-in condensate neutralizer raises the pH of the water so it can be safely discharged into the drain.

EXCLUSIVE HOT START PROGRAMMING icon

EXCLUSIVE HOT START PROGRAMMINGWhen the tap is turned off and the initial call for hot water is complete, a typical tankless unit will shut down immediately. Rheem Tankless Water Heaters remain in a ready-fire position for five minutes after use, reducing the cold water sandwich effect in back-to-back usage.

HARD WATER BUILDUP WARNING icon

HARD WATER BUILDUP WARNINGHard water that can lead to scale buildup is common in many parts of the country, and left untreated, can reduce the unit's efficiency and ability to provide hot water. Our built-in service alert automatically displays in the event the water heater detects scale buildup.

RACK KITThe Rheem® EZ Rack Kit mounts one or multiple tankless water heaters for indoor or outdoor applications. Compactly packaged, it can be assembled on site and configured for free standing—holding one unit or two units back-to-back—or wall mounted with a hanging bracket attached to the wall. Plus, it is expandable by adding tankless rack accessory kits.

SERVICE VALVES INCLUDED icon

SERVICE VALVES INCLUDEDEvery Rheem Commercial Tankless unit includes service valves. With their installation on cold inlet and hot outlet pipes, it can be isolated into individual units. This way, it's easy to identify the unit that requires flushing or other maintenance—all without shutting down the entire bank of tankless units.

COMMON VENT COMPATIBLE icon

COMMON VENT COMPATIBLECommon vent up to eight units with the Rheem header kits, complete with non-return valves. Elbows and termination kits are also available. Venting multiple units together saves space and materials and reduces outside wall penetrations.

Side-to-side clearance is only 1/2 inch, which saves valuable space
