It holds 36 gallons in the test, 4 gallons less than its 40-gallon sold size. Over one hour from a full tank, it gave 60 gallons in the test (its first-hour rating). Reheating lets it give 24 gallons beyond the 36 gallons in its tank.
It has 4 model numbers that are ENERGY STAR certified. In the test, it delivered 3.50 units of hot water energy for each unit used (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.
The test figures are not all the same for its 4 model numbers.
It may qualify for 18 rebate programs. Another 6 rebate programs may accept it if it meets their other terms.
