STATE ENLB-50 1**

This site calculated the 3,493 kWh figure; the registry does not list it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium draw pattern. For the STATE ENLB-50 1**, the UEF is 0.93, from the DOE CCD retrieved 2026-09-19. Among the 426 electric tank models at this draw pattern, this model ranks 153rd lowest for energy use. That puts it 38 kWh a year below the class median. The data does not show how much of that gap would appear in a real home, because the figure holds only at the test's daily draw. The steps are set out in how the annual energy and cost figures are calculated.

The medium draw pattern stands for a typical mid-sized household on a busy morning. The 3,493 kWh figure applies to homes whose daily use is close to that pattern. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 60 gallons. Its rated volume is 44 gallons. A household that uses well above the medium pattern falls outside the test condition, so the annual figure does not describe that household. The data does not show this model's energy use at any other draw. To compare this unit with others in the same class, use the same-class replacement search by model number.

This text does not give a running cost. The cost depends on your own utility's electricity tariff applied to the 3,493 kWh yearly use. The cost calculator for your own ZIP works it out from the rate where you live. The yearly cost gap against a median unit also depends on that rate, so the 38 kWh energy difference is not converted into a cost here. The installed price range appears in its own block with its source and date. That range is a modeled installed cost, not an installer's quote. The energy use, class rank and UEF on this page all come from the same test condition described above.
