It holds 47 gallons in the test, 3 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 58 gallons in the test (its first-hour rating). That is 11 gallons more than its tank holds, since it reheats during the hour. Of 481 heat pump models, 414 give more hot water in the first hour. The median heat pump model gives 72 gallons in the first hour of the test.

It is ENERGY STAR certified under its single model number. In the test, it gives 3.46 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 simulated a day of medium hot water use (its draw pattern). Of 226 heat pump models with the same draw pattern, 182 have a higher UEF. For its type and draw pattern, the median UEF is 3.68. While it reheats, the water gains 373% of the energy it uses (its recovery efficiency).

Its test figures match those of 2 other basic models. Those basic models are sold with Noritz and VAUGHN THERMAL as their brand names.

It may qualify for 17 rebate programs. Another 5 rebate programs may accept it if it meets their other terms.
