It holds 68 gallons in the test, 2 gallons more than its 66-gallon sold size. Over one hour from a full tank, it gave 76 gallons in the test (its first-hour rating). That is 8 gallons more than its tank holds, since it reheats during the hour. Among 481 heat pump models, 186 have a higher first-hour rating. Among heat pump models, the median first-hour rating is 72 gallons.

Its single model number, HPVX-66-DHPT 2**, is ENERGY STAR certified. In the test, it delivered 3.20 units of hot water energy for each unit used (its UEF). A UEF above 1 is possible because it moves heat from the air into the water. Its test ran at the high level of daily hot water use. Its UEF is lower than that of 226 of the 237 heat pump models with its draw pattern. On its draw pattern, the median heat pump UEF is 3.88. While it reheats, the water gains 368% of the energy it uses (its recovery efficiency).

Its test figures match those of 4 other basic models. Each of the 4 other brands lists one of them. For the full group, see the A. O. Smith HPTV-66 2**.
