Introducing the Rheem^® RTG-R Series Tankless Gas Water Heaters with Built-In Recirculation for Faster Hot Water and Faster Installs

Rheem proudly introduces the next evolution of non-condensing tankless water heating: the RTG-R Series with built-in recirculation. This tankless gas water heater maintains the proven performance, modern design, and contractor friendly installation and service features of the RTG Series—now enhanced with the added benefit of built in recirculation. It combines trusted Rheem performance with upgraded technology and improved installation experience for contractors, all while delivering comfort, convenience, and efficiency homeowners expect.

Built-In Recirculation for Faster Hot Water and Water Savings

The standout feature of the RTG-R model is the built-in recirculation. This integrated pump significantly reduces wasted water and wait times at the tap by keeping hot water ready to deliver more quickly whenever a faucet opens. This product can save homeowners up to 12,000 gallons of water every year, translating to more than $1,000 in water savings over a 15-year period. The RTG R with built in recirculation offers convenience while also helping reduce environmental impact through lower water waste and more efficient system operation.

Sustainability and Energy Efficiency at the Core

Sustainability remains central to Rheem’s design philosophy. The RTG-R Series uses up to 25% less energy than a standard 50-gallon gas tank water heater, which helps lower carbon footprint and reduce energy usage in the home. These models also reduce greenhouse gas NOx emissions by up to 65%, contributing to improved air quality while still delivering exceptional hot water performance.

Designed with Contractors in Mind

For contractors, the RTG-R integrated recirculation offers clear advantages. The units are smaller, lighter and easier to work with, making installation more efficient and servicing less time consuming. With industry best clearances of just a half inch side to side and in the front, installers have more flexibility in tight applications such as closets and compact utility spaces. Servicing is simplified as well, since a basic Phillips screwdriver is all that is required for disassembly, and the front door is designed to slide down and hang for easy access.

Smart Technology for Greater Control and Peace of Mind

Smarter technology elevates the homeowner experience even further. Models equipped with Wi-Fi use Rheem’s EcoNet^® platform, allowing full control from a smartphone. Users can adjust temperature settings, schedule the recirculation pump on RTG-R models, track water and energy usage and receive maintenance alerts. On indoor Wi-Fi models, LeakGuard^™ adds an extra layer of security by detecting leaks and automatically shutting off the water supply, reducing the risk of damage.

Reliable Performance and Installation Flexibility

The RTG-R-Series maintains the consistent performance that has built Rheem’s reputation. Its durable copper heat exchanger promotes fast heat transfer, while exclusive Hot Start Programming^™ minimizes cold water bursts when hot water is turned back on shortly after use. An overheat film wrap provides an additional safeguard by shutting down the system if temperatures exceed safe thresholds. Flexible installation is further supported by universal venting compatibility and the ability to run vent lengths up to 43 feet, giving contractors more options across various home layouts.

Powerful Output and Trusted Warranty Coverage

Flow rate options across the RTG-R-Series support up to three and a half bathrooms depending on the model and temperature rise. With gas input rates reaching up to 199,900 BTU/h and a Uniform Energy Factor (UEF) of 0.82, the units offer powerful performance while maintaining energy efficiency. Homeowners can install the system with confidence thanks to Rheem’s strong warranty coverage, which includes 15-years on the heat exchanger, 5-years years on parts and 1-year on labor.

The Next Generation of Tankless Performance

With the introduction of the RTG-R with built-in recirculation, Rheem is offering homeowners a smarter, more sustainable and more convenient tankless water heating solution. The RTG-R is designed not only to deliver endless hot water but also to save energy and water, reduce waiting time, simplify installation and provide modern control and monitoring features. For contractors and homeowners alike, it represents the next generation of tankless performance.
