UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 26 gallons in the test, 2 gallons less than its 28-gallon sold size. Starting full, it gives 43 gallons of hot water in its first hour of use. Reheating lets it give 17 gallons beyond the 26 gallons in its tank. In the first hour, 405 of the 477 electric storage models give more hot water. Among electric storage models, the median first-hour rating is 55 gallons.

In tests, 89% of the energy went to hot water, so its UEF is 0.89. Its test simulated a day of low hot water use (its draw pattern). Of 157 electric storage models with the same draw pattern, 136 have a higher UEF. For its type and draw pattern, the UEF runs from 0.88 to 0.95. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).

Its 3 model numbers are E10N-30LB 1**, E6N-30LB 1**, and NE3F30LBD 1**. All of its test figures are shared by 3 other basic models. Of those, one or more are under the A. O. Smith, RELIANCE WATER HEATERS, and State brands. For the full group, see the A. O. Smith ENLB-30 1**.
