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

It holds 54 gallons in the test, 1 gallon less than its 55-gallon sold size. It delivers 58 gallons of hot water in the test's first hour. Its tank holds 54 gallons, so reheating adds 4 gallons during the first hour. Of 477 electric storage models, 168 give more hot water in the first hour. The median electric storage model gives 55 gallons in its first hour.

In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). In the test, daily hot water use was set to medium (its draw pattern). Of 297 electric storage models with the same draw pattern, 81 have a higher UEF and 2 a lower one. For its type and draw pattern, its UEF sits at the median. When it reheats water in the test, 98% of the energy it uses ends up in the water.
