The Rheem RTE 13 Electric Tankless Water Heater is an ideal way to provide constant hot water to a single shower unit. It takes up just about one third of the space that a traditional water heater does and features a minimum activation flow of 4.0 GPM. This makes it the perfect electric tankless water heater for low-flow units, WaterSense units, and any other unit that does not draw much water. The Rheem RTE 13 Tankless Water Heater also has on-unit temperature control to conveniently provide you full control.

Equipped with LED indicator lights that informs you of the state at any moment, the Rheem RTE 13 also features an exclusive Overheat Film Wrap (OFW) that observes the temperature of the heat exchange and will immediately shut the electric tankless water heater down if the temperatures exceeds a safe level.

Fitment & Construction

The Rheem RTE 13 Electric Water Heater fits standard 1/2 inch NPT water connections. Constructed of rugged brass and copper, it's durable and built to last! The Rheem RTE 13 Indoor Tankless Water Heater has a maximum flow rating of 4.00 GPM.
