At Rheem, we're determined to become the go-to solution for commercial tankless

Commercial Tankless Features & Benefits

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.

MANIFOLD Control READYTo create a load sharing system, the factory-installed manifold control translator allows up to 20 units to be connected in daisy-chain-side-by-side configuration with the included cable. The system is load-balanced to create redundancy, so if one heater goes down, the business stays up and running.

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

Service notification settingThe Rheem exclusive Maintenance Alert Setting is activated 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.

The system is load-balanced to create redundancy, so if one heater goes down, the business stays up and running.

exclusive water savings settingSet by the contractor upon installation, this feature immediately reduces water waste by reducing water flow at the tap until the water heats to the preferred temperature—saving up to 1,100 gallons of water per year.

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 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. Rheem's 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.

standardized maintenance schedulesEvery 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.
