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. Starting full, it gives 67 gallons of hot water in its first hour of use. Its tank holds 46 gallons, so reheating adds 21 gallons during the first hour. Of 477 electric storage models, 51 give more hot water in the first hour. The median electric storage model gives 55 gallons in the first hour of the test.
In tests, 92% of the energy it uses ends up as hot water (UEF 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. For its type and draw pattern, its UEF sits at the median. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
It is sold under 4 model numbers in all. There are 7 more basic models with the same test figures. Each of them is listed under a different brand. You can find the whole group on the page for the A. O. Smith HESF-50 1**.
