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 84 gallons in the test (its first-hour rating). Its tank holds 82 gallons, so reheating adds 2 gallons during the first hour. Of 481 heat pump models, 112 give more hot water in the first hour. Among heat pump models, the median first-hour rating is 72 gallons.

Its single model number, FPTU-80 1**, is ENERGY STAR certified. In the test, it gives 3.45 units of hot water energy per unit it uses (its UEF).
