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 84 gallons of hot water in the test's first hour. Reheating lets it give 46 gallons beyond the 38 gallons in its tank. Of 763 gas storage models, 209 give more hot water in the first hour. 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, 66% of the energy went to hot water, so its UEF is 0.66.

For its type and draw pattern, its UEF sits at the median. When it reheats water in the test, 80% of the energy it uses ends up in the water.
