It holds 67 gallons in the test, 1 gallon more than its 66-gallon sold size. Over one hour from a full tank, it gave 79 gallons in the test (its first-hour rating). Its tank holds 67 gallons, so reheating adds 12 gallons during the first hour. In the first hour, 165 of the 481 heat pump models give more hot water. Among heat pump models, the median first-hour rating is 72 gallons.

The single model number sold under it is ENERGY STAR certified. For each unit of energy it uses, 3.45 units end up in the hot water (its UEF). A UEF above 1 is possible because it moves heat from the air into the water. Its test simulated a day of high hot water use (its draw pattern). Of 237 heat pump models with the same draw pattern, 199 have a higher UEF and 21 a lower one. For its type and draw pattern, the UEF runs from 2.85 to 4.95. Its recovery efficiency is 265%, because it takes heat from the air as it reheats water.

All of its test figures are shared by 5 other basic models. Each of them is listed under a different brand. For the full group, see the A. O. Smith HPTU-66N 1**.
