STATE ENJ-40 1**
0.93 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
Checking the STATE ENJ-40 1**? It uses 3,493 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 38 kWh below the 3,531 kWh median of the 426 electric tank models registered at the same draw pattern.
Energy use per year
3,493 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is below the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 153 of 426, lowest energy first.
Solid line: this model (3,493 kWh). Dashed line: the class median.

The 3,493 kWh figure is computed by this site, not taken from the registry. It combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium pattern. The registry lists a UEF of 0.93 for this unit, retrieved from the DOE CCD on 2026-09-19. At that UEF and draw, it ranks 153rd lowest in energy use of the 426 electric tank models at the medium draw pattern. That places it in the second-lowest quarter of its class. At the test draw, it sits 38 kWh a year below the class median. The registry does not show how that gap changes at other usage levels, so that figure is not available. The full method is set out in how the annual cost is calculated.
In the DOE test, the medium draw pattern represents the daily hot-water use of a typical mid-sized household. The 3,493 kWh figure applies only to that level of use. The unit's first hour rating, the gallons of hot water available in the first hour from a full tank, is 54 gallons. Its rated volume is 35 gallons. A household whose busiest hour stays within 54 gallons matches the conditions behind these figures. A household that draws more in its busiest hour falls outside those conditions. Annual energy for a heavier or lighter pattern is not available for this model. For a like-for-like swap, you can find a same-class replacement by model number. To compare by fuel or tank size, use the selector by fuel, space and size.
Running cost is not stated in this text because it depends on your own utility's electricity tariff. The page computes it from the 3,493 kWh at the medium draw pattern and the rate for your ZIP. The cost calculator on your own ZIP shows that result. The same applies to the 38 kWh gap to the class median: its yearly value depends on your tariff. The modeled installed-cost range appears in its own block with its source and date. It is a model, not a quote, and this text does not restate it. If your household's use differs from the test draw, both energy use and cost will differ. The registry does not show by how much.
