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

It holds 43 gallons in the test, 4 gallons less than its 47-gallon sold size. Starting full, it gives 54 gallons of hot water in its first hour of use. Reheating lets it give 11 gallons beyond the 43 gallons in its tank. Among 477 electric storage models, 239 have a higher first-hour rating. The median electric storage model gives 55 gallons in its first hour.

In tests, 92% of the energy went to hot water, so its UEF is 0.92. The daily hot water use in the test, called its draw pattern, was medium. Among 297 electric storage models on its draw pattern, 81 have a higher UEF. 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).

Its 2 model numbers are PROE47 S2 RH CG and XE47S06CG45U0. Its test figures match those of 3 other basic models. Those basic models are sold with Friedrich, Richmond, and Ruud as their brand names.
