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 66 gallons in the test (its first-hour rating). Its tank holds 40 gallons, so reheating adds 26 gallons during the first hour. Of 477 electric storage models, 59 give more hot water in the first hour. The median electric storage model gives 55 gallons in its first hour.
In the test, 8% of its energy does not reach the hot water (UEF 0.92). In the test, daily hot water use was set to medium (its draw pattern). 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. When it reheats water in the test, 98% of the energy it uses ends up in the water.
It is sold as GE40S08BAM01 and GE40S10BAM01. Its test figures match those of one other basic model.
