UEF is the uniform energy factor. A dash means the model has no such figure.
Sold as 55 gallons, it holds 55 gallons in the test. Starting full, it gives 75 gallons of hot water in its first hour of use. Reheating lets it give 20 gallons beyond the 55 gallons in its tank. Among 477 electric storage models, 14 have a higher first-hour rating. The median electric storage model gives 55 gallons in its first hour.
In tests, 94% of the energy it uses ends up as hot water (UEF 0.94). Its test ran at the high level of daily hot water use. Among 23 electric storage models with its draw pattern, none reaches a higher UEF than this one. For its type and draw pattern, its UEF sits at the median. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
It is sold as EE6U-55H 1** and EEA8F-55H 1**. There are 4 more basic models with the same test figures. They are listed under 4 other brands, one each. For the full group, see the A. O. Smith HETF-55 1**.
