UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 37 gallons in the test, 3 gallons less than its 40-gallon sold size. Starting full, it gives 46 gallons of hot water in its first hour of use. Reheating lets it give 9 gallons beyond the 37 gallons in its tank. Among 477 electric storage models, 368 have a higher first-hour rating. 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). Its test ran at the low level of daily hot water use. Of 157 electric storage models with the same draw pattern, 12 have a higher UEF. For its type and draw pattern, its UEF sits at the median. The water took in 98% of the energy used to reheat it (its recovery efficiency).
All of its test figures are shared by 2 other basic models. The Hubbell and VAUGHN THERMAL brands list one or more of them. You can find the whole group on the page for the Hubbell ME-40.
