Rheem PROUH50 T2 RH350BM

It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 67 gallons in the test (its first-hour rating). Reheating lets it give 22 gallons beyond the 45 gallons in its tank. In the first hour, 287 of the 481 heat pump models give more hot water. Among heat pump models, the median first-hour rating is 72 gallons.

Under this basic model, 2 model numbers are ENERGY STAR certified. In the test, it delivered 3.50 units of hot water energy for each unit used (its UEF). Pulling heat from the air lets its UEF pass 1. In the test, daily hot water use was set to medium (its draw pattern). Among 226 heat pump models on its draw pattern, 158 have a higher UEF. For its type and draw pattern, the median UEF is 3.68. While it reheats, the water gains 400% of the energy it uses (its recovery efficiency).

All of its test figures are shared by 11 other basic models. The Friedrich and Ruud brands list one or more of them. For the full group, see the Rheem PRO H50 T2 RH310BM page.

It may qualify for 18 rebate programs in 18 states. Another 6 programs may accept it if it meets their other terms.
