It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. It delivers 51 gallons of hot water in the test's first hour. Its tank holds 46 gallons, so reheating adds 5 gallons during the first hour. Of 481 heat pump models, 455 give more hot water in the first hour. The median heat pump model gives 72 gallons in its first hour.
Its single model number, PROUH50 T0 RU120, is ENERGY STAR certified. For each unit of energy it uses, 3.00 units end up in the hot water (its UEF). It moves heat from the air rather than making it, so its UEF passes 1. The daily hot water use in the test, called its draw pattern, was medium. Of 226 heat pump models with the same draw pattern, 208 have a higher UEF. For its type and draw pattern, the median UEF is 3.68. When it reheats water in the test, the water gains 350% of the energy it uses.
There are 3 more basic models with the same test figures. Those basic models are sold with Friedrich, Rheem, and Richmond as their brand names. For the full group, see the Rheem PROPH50 T0 RH120.
