More Hot Water

Vacation Mode and Eco Mode features allow switching off power to the tank when it isn’t needed, saving energy on water heating

Saves Money

Requires only a one-pro install, takes as little as 45 minutes, and Vacation Mode helps save money on energy bills

Installed on an existing tank or mounted nearby on the wall, it gives a 50-gal. tank the capacity of an 80-gal. tank, without taking up more space

Water Heater Booster Product Overview

Compatible with both electric and gas tanks, the Rheem Water Heater Booster installs directly to the tank’s hot water outlet or mounts on a nearby wall. It significantly improves the performance of tank-type water heaters by increasing the gallons of hot water delivered and energy efficiency. In fact, it only activates when it senses the water has dropped below the activation temperature.
