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. It delivers 57 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. In the first hour, 177 of the 477 electric storage models give more hot water. Among electric storage models, the median first-hour rating is 55 gallons.

In tests, 93% of the energy it uses ends up as hot water (UEF 0.93). The daily hot water use in the test, called its draw pattern, was medium. Its UEF is lower than that of 20 of the 297 electric storage models with its draw pattern. For its type and draw pattern, the UEF runs from 0.91 to 0.95. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).

There are 2 more basic models with the same test figures. The Ranein and Vancepic brands list one or more of them.
