Upgrade to the Ultimate in Tankless and Efficiency

Your water heater keeps your household running with hot water for showers, dishes, handwashing, baths, cleaning, laundry and more. Our newest tankless product – Rheem^® RTGH Series Super High Efficiency Condensing Tankless Water Heater – delivers the ultimate comfort plus savings.

Ultimate Comfort in Continuous Hot Water

You’ll have enough hot water to load the laundry, wash the dishes and bathe the kids. Always having hot water means you don’t have to wait to get things done or experience a cold shower. Rheem-exclusive Hot Start Programming™ eliminates cold water bursts for continuous hot water, even in start and stop situations.

Efficiency That Pays Off

The industry-exclusive features give you a new level of efficiency. The Rheem-exclusive water saving setting saves up to 1,100 gallons of water per year¹ by reducing water flow rate until water has reached the set point.

Since it only operates when you need it and has an efficient condensing heat exchanger, you’ll save on energy costs. This water heater uses up to 34% less energy than a standard 50-gallon tank water heater² while minimizing your impact on the environment.

Smart Features Give You the Control

Built-in Wi-Fi technology models allow you to optimize settings like temperature, set vacation/away mode, activate water saving setting and receive leak detection alerts through the user-friendly EcoNet® app. Ask your insurance company if the LeakGuard™ leak detection system with LeakSense™ and auto shut-off valve (select indoor Wi-Fi models) qualifies for homeowners insurance discounts3.
