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. Over one hour from a full tank, it gave 63 gallons in the test (its first-hour rating). Reheating lets it give 18 gallons beyond the 45 gallons in its tank. Among 477 electric storage models, 99 have a higher first-hour rating. The median electric storage model gives 55 gallons in its first hour.

In tests, 92% of the energy went to hot water, so its UEF is 0.92. The daily hot water use in the test, called its draw pattern, was medium. 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. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).

It is sold under 4 model numbers in all. All of its test figures are shared by 12 other basic models. In all, 6 other brands list one or more of them. For the full group, see the Rheem XE50M12CS55U1.
