It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. Starting full, it gives 52 gallons of hot water in its first hour of use. Its tank holds 46 gallons, so reheating adds 6 gallons during the first hour. In the first hour, 439 of the 481 heat pump models give more hot water. The median heat pump model gives 72 gallons in its first hour.

The single model number sold under it is ENERGY STAR certified. In the test, it gives 3.00 units of hot water energy per unit it uses (its UEF). A UEF above 1 is possible because it moves heat from the air into the water. Its test simulated a day of medium hot water use (its draw pattern). Of 226 heat pump models with the same draw pattern, 208 have a higher UEF and 5 a lower one. A UEF of 3.68 is the median for its type and draw pattern. When it reheats water in the test, the water gains 457% of the energy it uses.

Its test figures match those of 4 other basic models. They are listed under 4 other brands, one each. For the full group, see the A. O. Smith HPTV-50 2**.
