UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 52 gallons in the test, 3 gallons less than its 55-gallon sold size. Starting full, it gives 64 gallons of hot water in its first hour of use. Its tank holds 52 gallons, so reheating adds 12 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). The daily hot water use in the test, called its draw pattern, was medium. Of 297 electric storage models with the same draw pattern, 81 have a higher UEF. Its UEF is the median for its type and draw pattern. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).

All of its test figures are shared by 2 other basic models. The Hubbell and VAUGHN brands list one or more of them. For the full group, see the Hubbell ME55 page.
