| Model number | Storage volume (gal) | UEF | First-hour rating (gal) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|---|

UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. It delivers 60 gallons of hot water in the test's first hour. That is 15 gallons more than its tank holds, since it reheats during the hour. Among 477 electric storage models, 145 have a higher first-hour rating. The median electric storage model gives 55 gallons in its first hour.
In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). Its test simulated a day of medium hot water use (its draw pattern). 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. The water took in 98% of the energy used to reheat it (its recovery efficiency).
Its 2 model numbers are ES50M* and LCE50M*. There are 6 more basic models with the same test figures. In all, 4 other brands list one or more of them. For the full group, see the Bradford White RE250S*-*****.
