UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 39 gallons in the test, 1 gallon less than its 40-gallon sold size. It delivers 64 gallons of hot water in the test's first hour. That is 25 gallons more than its tank holds, since it reheats during the hour. Of 763 gas storage models, 629 give more hot water in the first hour. Among gas storage models, the median first-hour rating is 78 gallons.
On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 60% of the energy went to hot water, so its UEF is 0.60. In the test, daily hot water use was set to medium (its draw pattern). Its UEF is lower than that of 88 of the 288 gas storage models with its draw pattern. Its UEF is the median for its type and draw pattern. Of the energy spent to reheat water, 75% goes into it (its recovery efficiency).
