It holds 82 gallons in the test, 2 gallons more than its 80-gallon sold size. Over one hour from a full tank, it gave 86 gallons in the test (its first-hour rating). Reheating lets it give 4 gallons beyond the 82 gallons in its tank. In the first hour, 100 of the 481 heat pump models give more hot water. The median heat pump model gives 72 gallons in its first hour.

It has 3 model numbers that are ENERGY STAR certified. For each unit of energy it uses, 3.45 units end up in the hot water (its UEF).

Among 237 heat pump models on its draw pattern, 199 have a higher UEF. On its draw pattern, the median heat pump UEF is 3.88. When it reheats water in the test, the water gains 233% of the energy it uses.
