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

Sold as 50 gallons, it holds 50 gallons in the test. Over one hour from a full tank, it gave 75 gallons in the test (its first-hour rating). That is 25 gallons more than its tank holds, since it reheats during the hour. Of 477 electric storage models, 14 give more hot water in the first hour. The median electric storage model gives 55 gallons in the first hour of the test.

In tests, 93% of the energy went to hot water, so its UEF is 0.93. The daily hot water use in the test, called its draw pattern, was high. Among 23 electric storage models on its draw pattern, 13 have a higher UEF. On its draw pattern, the median electric storage UEF is 0.94. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).

It is the basic model for GE50S10BMM01 and GE50S10BUT01. All of its test figures are shared by one other basic model.
