Water Heater Booster

Water Heater Booster

The Rheem Water Heater Booster improves the overall performance and capacity of gas or electric tank water heaters.  The booster unit attaches to any tank or nearby wall.

Compatible with Electric or Gas Tank
The Rheem Water Heater Booster installs directly on the water line to provide more hot water than the tank alone can provide. The booster delivers nearly double the shower time. The unit senses the temperature of the water from the tank outlet, and activates when it senses that its inlet temperature has dropped below the user set activation temperature.

The Benefits of a Rheem Water Heater Booster
  • Increase hot water delivery up to 45%
  • Compact design
  • Dimensions:8-1/4" H x 12-5/8" W x 3-5/8" D
  • Digital user interface

  • Adjustable outlet temperature 80 - 140°F
  • Set temperature in increments of 1°F
  • Easy installation on new or existing water heater
  • Field replaceable element
Additional wiring maybe required for a gas tank installation.
