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 67 gallons of hot water in its first hour of use. Its tank holds 38 gallons, so reheating adds 29 gallons during the first hour. Among 763 gas storage models, 552 have a higher first-hour rating. The median gas storage model gives 78 gallons in the first hour of the test.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In the test, 41% of its energy does not reach the hot water (UEF 0.59). Its test simulated a day of medium hot water use (its draw pattern). Its UEF is lower than that of 185 of the 288 gas storage models with its draw pattern. For its type and draw pattern, the UEF runs from 0.57 to 0.75. Of the energy spent to reheat water, 78% goes into it (its recovery efficiency).
