UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 48 gallons in the test, 2 gallons less than its 50-gallon sold size. Starting full, it gives 77 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. In the first hour, 418 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.

On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In the test, 34% of its energy does not reach the hot water (UEF 0.66). In the test, daily hot water use was set to high (its draw pattern). Of 434 gas storage models with the same draw pattern, 213 have a higher UEF. On its draw pattern, its UEF is also the median gas storage UEF. The water took in 79% of the energy used to reheat it (its recovery efficiency).
