It holds 60 gallons in the test, 5 gallons less than its 65-gallon sold size. It delivers 80 gallons of hot water in the test's first hour. Reheating lets it give 20 gallons beyond the 60 gallons in its tank. In the first hour, 146 of the 481 heat pump models give more hot water. The median heat pump model gives 72 gallons in its first hour.

Its single model number, REHP65, is ENERGY STAR certified. In the test, it gives 3.90 units of hot water energy per unit it uses (its UEF). It moves heat from the air rather than making it, so its UEF passes 1. Its test ran at the high level of daily hot water use. Its UEF is lower than that of 97 of the 237 heat pump models with its draw pattern. For its type and draw pattern, the UEF runs from 2.85 to 4.95. Its recovery efficiency is 450%, because it takes heat from the air as it reheats water.
