Rheem Heat Pump Water Heater

Ecosense and Prestige Series'

The Rheem heat pump water heater is represented among a few different models:

  • Rheem Ecosense: A model which appears to be sold exclusively at Home Depot, is re-branded specifically for Home Depot. 
  • Rheem Prestige: This water heater is sold through approved Rheem dealers.
  • Ruud Prestige: Ruud is a division of Rheem. 

Each of the above models, although containing different branding names, are essentially the same.  So the discussion below applies to each of the models above.

Below are a few features that makes the Rheem heat pump water heater stand out among its competition:

  • The first hour rating of 57 gal/hr is very good for the size of the tank (50 gallons).
  • Rheem requires the water heater to be installed indoors in a room with a minimum size of 1000 cubic feet.  For a small water heater, this is not a very good requirement.  One of Rheem's competitors, Stiebel Eltron, is an 80 gallon heater but only requires a room sized at 800 cubic feet.
  • This water heater can be installed in a room that maintains only 37 degrees Fahrenheit.  If it is being installed in a garage, this can result in significant energy savings compared to most competition (e.g. G.E. requires 45 degrees).
  • Contains a magnesium anode rod which prevents the formation of rust.
  • There is a backup dry fire protection system in case the electric heating elements malfunction.
  • There are many useful operating modes; Vacation, High Demand, Electric Only, Energy Saver...and of course....Heat Pump.
  • Is capable of operating in a remote mode enabling the home owner to use it in conjunction with a central home control system.
