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 65 gallons in the test (its first-hour rating). That is 25 gallons more than its tank holds, since it reheats during the hour. In the first hour, 66 of the 477 electric storage models give more hot water. Among electric storage models, the median first-hour rating is 55 gallons.
In tests, 92% of the energy went to hot water, so its UEF is 0.92. In the test, daily hot water use was set to medium (its draw pattern). Of 297 electric storage models with the same draw pattern, 81 have a higher UEF and 2 a lower one. On its draw pattern, its UEF is also the median electric storage UEF. The water took in 98% of the energy used to reheat it (its recovery efficiency).
It is the basic model for GE40T08BAM01 and GE40T10BAM01. There are 2 more basic models with the same test figures. For the full group, see the GE GE40S10BMM01 page.
