It holds 36 gallons in the test, 4 gallons less than its 40-gallon sold size. Starting full, it gives 46 gallons of hot water in its first hour of use. That is 10 gallons more than its tank holds, since it reheats during the hour. Of 481 heat pump models, 460 give more hot water in the first hour. Among heat pump models, the median first-hour rating is 72 gallons.

Its single model number, XE40T10H22U0, is ENERGY STAR certified. For each unit of energy it uses, 3.45 units end up in the hot water (its UEF). A UEF above 1 is possible because it moves heat from the air into the water. The daily hot water use in the test, called its draw pattern, was low. Of 18 heat pump models with the same draw pattern, none has a higher UEF. For its type and draw pattern, its UEF sits at the median. While it reheats, the water gains 432% of the energy it uses (its recovery efficiency).

There are 9 more basic models with the same test figures. The Friedrich, Richmond, and Ruud brands list one or more of them. For the full group, see the Rheem PROPH40 T2 RH375-15.
