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

It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. It delivers 74 gallons of hot water in the test's first hour. That is 29 gallons more than its tank holds, since it reheats during the hour. Among 477 electric storage models, 23 have a higher first-hour rating. The median electric storage model gives 55 gallons in the first hour of the test.

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). Its UEF is lower than that of 81 of the 297 electric storage models with its draw pattern. Its UEF is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).

It is sold as EE6U-50H 1** and EEA8F-50H 1**. There are 4 more basic models with the same test figures. They are listed under 4 other brands, one each. You can find the whole group on the page for the A. O. Smith HETF-50 1**.
