UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 47 gallons in the test, 3 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 64 gallons in the test (its first-hour rating). Its tank holds 47 gallons, so reheating adds 17 gallons during the first hour. In the first hour, 74 of the 477 electric storage models give more hot water. The median electric storage model gives 55 gallons in the first hour of the test.
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). Of 297 electric storage models with the same draw pattern, 81 have a higher UEF. For its type and draw pattern, its UEF sits at the median. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
All of its test figures are shared by 4 other basic models. Of those, one or more are under the MRCOOL and Stream 33 brands.
