Rheem Tankless 7.4 Series
Continuous hot water on demand – Tankless water heaters provide a steady flow of hot water whenever it’s needed -- bath after bath, shower after shower.
Compact, space saving design – Rheem indoor and outdoor tankless water heaters are just over two-feet tall, weigh 55 pounds (or less), and can be attached to an interior or exterior wall.
Energy efficiency – Rheem tankless gas water heaters are more energy efficient than traditional water heaters because they eliminate the need to maintain a large supply of heated water. Rheem tankless water heaters qualify for up to a $300 energy tax credit.
Precise temperature delivery – Rheem tankless products put consumers in complete control of water temperature with a digital controller. A touch of the fingertip can adjust the maximum water temperature up or down to achieve the perfect comfort level for the individual user. This feature is ideal for families with young children and older adults.
Self-diagnostic program – Rheem tankless water heaters use smart technology. The built-in self-diagnostic program displays maintenance information when necessary. In the event an error is detected in the tankless unit, a code will be displayed for easy troubleshooting.
GAMA Certified – Rheem tankless water heaters are certified by GAMA, an independent testing agency for government standards and certifications. In fact, Rheem products meet or exceed all energy efficiency requirements
