UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 38 gallons in the test, 2 gallons less than its 40-gallon sold size. Starting full, it gives 67 gallons of hot water in its first hour of use. That is 29 gallons more than its tank holds, since it reheats during the hour. Of 763 gas storage models, 552 give more hot water in the first hour. Among gas storage models, the median first-hour rating is 78 gallons.
It was not listed as ENERGY STAR certified on Oct 26, 2026. In the test, 42% of its energy does not reach the hot water (UEF 0.58). In the test, daily hot water use was set to medium (its draw pattern). Among 288 gas storage models on its draw pattern, 230 have a higher UEF. For its type and draw pattern, the median UEF is 0.60. Of the energy spent to reheat water, 78% goes into it (its recovery efficiency).
