It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. It delivers 52 gallons of hot water in the test's first hour. That is 6 gallons more than its tank holds, since it reheats during the hour. Of 481 heat pump models, 439 give more hot water in the first hour. The median heat pump model gives 72 gallons in the first hour of the test.

All 2 of its model numbers are 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. Its test simulated a day of medium hot water use (its draw pattern). Its UEF is lower than that of 208 of the 226 heat pump models with its draw pattern. On its draw pattern, the median heat pump UEF is 3.68. When it reheats water in the test, the water gains 457% of the energy it uses.

It is the basic model for HPTV-50 2** and HPV10-50H01DV 2**. All of its test figures are shared by 4 other basic models. Each of the 4 other brands lists one of them.

It may qualify for 19 rebate programs in 20 states. Another 5 rebate programs may accept it if it meets their other terms.
