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

It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 62 gallons in the test (its first-hour rating). Reheating lets it give 16 gallons beyond the 46 gallons in its tank. Among 477 electric storage models, 124 have a higher first-hour rating. Among electric storage models, the median first-hour rating is 55 gallons.

In tests, 92% of the energy it uses ends up as hot water (UEF 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. 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).

It is the basic model for 6-50-EORT 1** and 9-50-EORT 1**. There are 5 more basic models with the same test figures. Each of them is listed under a different brand. For the full group, see the A. O. Smith ENT-50-1** page.
