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

Sold as 40 gallons, it holds 40 gallons in the test. Over one hour from a full tank, it gave 63 gallons in the test (its first-hour rating). That is 23 gallons more than its tank holds, since it reheats during the hour. Of 477 electric storage models, 99 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, 92% of the energy it uses ends up as hot water (UEF 0.92). Its test simulated a day of medium hot water use (its draw pattern). Its UEF is lower than that of 81 of the 297 electric storage models with its draw pattern. For its type and draw pattern, its UEF sits at the median. The water took in 98% of the energy used to reheat it (its recovery efficiency).

It is sold as GE40T08BAM02 and GE40T10BAM02.
