TO MEET CLIENT NEEDS

Introducing Rheem® Commercial Condensing Tankless Water Heaters—the most popular brand of tankless water heaters1—and the best option for commercial projects and applications. This ever-expanding commercial tankless line now includes eight new units with four built-in manifold control ready options and common venting availability on all indoor models.

Commercial Ready

Rheem Commercial Tankless Water Heaters are made for hardworking environments, with high-temp chip factory-installed

System Redundancy

Select models allow up to 20 units to be daisy-chained together via the included manifold control cable

Rheem EZ Rack™ Kit

Compactly packaged, it can be assembled on site and configured for any installation scenario

Built-in Condensate Neutralizer

The built-in condensate neutralizer raises the pH of the water so it can be safely discharged into the drain, preventing corrosion and damage

Service Notification Setting

Proper 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

EcoNet Upgradeable

Add an EcoNet® WiFi Kit for the ability to control and monitor single or manifolded water heaters from anywhere2. EcoNet also sends mobile reminders when it’s time for maintenance. And if it detects a water leak, it shuts off gas and water to prevent damage3.

Overheat Detection Override

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

Exclusive Hot Start Programming

When 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

Hard 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.

Service Valves Included

Every 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

Common 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.

All variants are ready for U.S. and Canada.
Note: Manifold control ready units can be daisy chained together. If you have the heaters common vented, you can still manifold up to 20 units, you just have to limit the common venting to 10 units maximum. Each manifold control ready unit comes with a cable for connection. (No MIC-6 or MIC-185 required for manifold control ready models; MIC-6 and MIC-185 controllers can still be used with commercial tankless models.) 180k and 157k BTU/h models will remain available as residential models that can be converted for commercial use by purchasing the Commercial Program Chip Accessory.
