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 73 gallons of hot water in its first hour of use. That is 35 gallons more than its tank holds, since it reheats during the hour. Among 763 gas storage models, 477 have a higher first-hour rating. 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, 67% of the energy went to hot water, so its UEF is 0.67. Its test ran at the medium level of daily hot water use. Among 288 gas storage models on its draw pattern, 19 have a higher UEF. A UEF of 0.60 is the median for its type and draw pattern.
