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 75 gallons of hot water in the test's first hour. Reheating lets it give 25 gallons beyond the 50 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, 93% of the energy it uses ends up as hot water (UEF 0.93). Its test ran at the high level of daily hot water use. Its UEF is lower than that of 13 of the 23 electric storage models with its draw pattern. 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 2 model numbers are GE50S10BLM01 and GE50S12BLM01. Its test figures match those of one other basic model. For the full group, see the GE GE50S10BMM01.
