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

It holds 54 gallons in the test, 1 gallon less than its 55-gallon sold size. Starting full, it gives 58 gallons of hot water in its first hour of use. Reheating lets it give 4 gallons beyond the 54 gallons in its tank. In the first hour, 168 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). Its test simulated a day of medium hot water use (its draw pattern). Among 297 electric storage models on its 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. Those basic models are sold with Hubbell and VAUGHN THERMAL as their brand names. For the full group, see the Hubbell MP55F.
