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

It holds 36 gallons in the test, 4 gallons less than its 40-gallon sold size. It delivers 60 gallons of hot water in the test's first hour. Reheating lets it give 24 gallons beyond the 36 gallons in its tank. In the first hour, 145 of the 477 electric storage models give more hot water. The median electric storage model gives 55 gallons in the first hour of the test.

In tests, 92% of the energy went to hot water, so its UEF is 0.92. The daily hot water use in the test, called its draw pattern, was medium. Of 297 electric storage models with the same draw pattern, 81 have a higher UEF and 2 a lower one. On its draw pattern, its UEF is also the median electric storage UEF. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
