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. It delivers 73 gallons of hot water in the test's first hour. Its tank holds 38 gallons, so reheating adds 35 gallons during the first hour. In the first hour, 477 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 tests, 67% of the energy it uses ends up as hot water (UEF 0.67).

For its type and draw pattern, the median UEF is 0.60. Of the energy spent to reheat water, 79% goes into it (its recovery efficiency).
