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

It holds 96 gallons in the test, 4 gallons less than its 100-gallon sold size. Starting full, it gives 86 gallons of hot water in its first hour of use. Among 21 grid-enabled models, 7 have a higher first-hour rating. The median grid-enabled model gives 85 gallons in the first hour of the test.

In tests, 93% of the energy went to hot water, so its UEF is 0.93. Its test simulated a day of high hot water use (its draw pattern). Of 21 grid-enabled models with the same draw pattern, none has a higher UEF. For its type and draw pattern, the median UEF is 0.92. The water took in 98% of the energy used to reheat it (its recovery efficiency).
