It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 67 gallons in the test (its first-hour rating). Its tank holds 45 gallons, so reheating adds 22 gallons during the first hour.
It is ENERGY STAR certified under its single model number. In the test, it gives 3.88 units of hot water energy per unit it uses (its UEF). It moves heat from the air rather than making it, so its UEF passes 1. Its test ran at the medium level of daily hot water use.
