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

It holds 29 gallons in the test, 1 gallon less than its 30-gallon sold size. Over one hour from a full tank, it gave 55 gallons in the test (its first-hour rating). Reheating lets it give 26 gallons beyond the 29 gallons in its tank. Among 763 gas storage models, 727 have a higher first-hour rating. The median gas storage model gives 78 gallons in the first hour of the test.

On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 60% of the energy it uses ends up as hot water (UEF 0.60). The daily hot water use in the test, called its draw pattern, was medium. Of 288 gas storage models with the same draw pattern, 88 have a higher UEF. On its draw pattern, its UEF is also the median gas storage UEF. Of the energy spent to reheat water, 75% goes into it (its recovery efficiency).
