UEF is the uniform energy factor. A dash means the model has no such figure.
Over one hour from a full tank, it gave 65 gallons in the test (its first-hour rating). Its tank holds 51 gallons, so reheating adds 14 gallons during the first hour. Among 477 electric storage models, 66 have a higher first-hour rating. Among electric storage models, the median first-hour rating is 55 gallons.
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. Of 297 electric storage models with the same draw pattern, 81 have a higher UEF and 2 a lower one. 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).
