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. It delivers 78 gallons of hot water in the test's first hour. That is 28 gallons more than its tank holds, since it reheats during the hour. In the first hour, 2 of the 477 electric storage models give more hot water. Among electric storage models, the median first-hour rating is 55 gallons.

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. Of 23 electric storage models with the same draw pattern, 13 have a higher UEF. A UEF of 0.94 is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).

Its 3 model numbers are GE50T10BLM01, GE50T10BQT01, and GE50T12BLM01. Its test figures match those of one other basic model. You can find the whole group on the page for the GE GE50T10BAM02.
