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. Over one hour from a full tank, it gave 89 gallons in the test (its first-hour rating). Its tank holds 48 gallons, so reheating adds 41 gallons during the first hour. In the first hour, 129 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 61% of the energy it uses ends up as hot water (UEF 0.61). In the test, daily hot water use was set to high (its draw pattern). Among 434 gas storage models on its draw pattern, 419 have a higher UEF. A UEF of 0.66 is the median for its type and draw pattern. Of the energy spent to reheat water, 77% goes into it (its recovery efficiency).
