It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. It delivers 87 gallons of hot water in the test's first hour. That is 41 gallons more than its tank holds, since it reheats during the hour. In the first hour, 143 of the 763 gas storage models give more hot water. Among gas storage models, the median first-hour rating is 78 gallons.
As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 80% of the energy it uses ends up as hot water (UEF 0.80). Its test ran at the high level of daily hot water use. Among 434 gas storage models on its draw pattern, 50 have a higher UEF. On its draw pattern, the median gas storage UEF is 0.66. When it reheats water in the test, 89% of the energy it uses ends up in the water.
