UEF is the uniform energy factor. A dash means the model has no such figure.
It delivers 42 gallons of hot water in the test's first hour. That is 17 gallons more than its tank holds, since it reheats during the hour. Of 477 electric storage models, 416 give more hot water in the first hour. Among electric storage models, the median first-hour rating is 55 gallons.
In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). In the test, daily hot water use was set to low (its draw pattern). Its UEF is lower than that of 12 of the 157 electric storage models with its draw pattern. On its draw pattern, its UEF is also the median electric storage UEF. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
All of its test figures are shared by one other basic model. That one carries the Vancepic brand name.
