UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. It delivers 62 gallons of hot water in the test's first hour. That is 16 gallons more than its tank holds, since it reheats during the hour. Of 477 electric storage models, 124 give more hot water in the first hour. 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. Its UEF is lower than that of 81 of the 297 electric storage models with its draw pattern. Its UEF is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).
It is sold under 6 model numbers in all. Its test figures match those of 5 other basic models. Each of them is listed under a different brand. You can find the whole group on the page for the A. O. Smith ENT-50-1**.
