0.92 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).
If you are checking the STATE ENLB-40 1**, this electric tank uses 3,531 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. Among the 426 electric tank models at that pattern, it equals the class median of 3,531 kWh, a difference of 0 kWh.
Energy use per year
3,531 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 equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

The 3,531 kWh figure is calculated by this site. The registry does not publish 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 pattern. This model's UEF is 0.92, taken from the DOE CCD retrieved 2026-09-19. DOE defines the medium pattern as a typical household's daily use, including a busy morning. A home that draws more or less hot water than that test day will use a different amount of electricity. That amount is not available here, because the figure applies only at the test's draw. The full steps are set out in how the annual cost is calculated, including where the daily draw comes from.
Among the 426 electric tank models registered at the medium draw pattern, this unit ranks 213th lowest for energy use. Together with the median match noted above, this puts it in the second-lowest quarter of its class. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. Its rated volume is 35 gallons. The first hour rating fits a home whose busiest hour needs no more than 51 gallons of hot water. A home that needs more than that in one hour may run short with this unit. If you want energy use below the class median, the models with a lower energy rank use less at the same pattern. A plumber matching a like-for-like unit can find a same-class replacement by model number.
This text does not state a running cost. The cost depends on your own utility's electricity tariff, and this page does not know it. The cost calculator on your own ZIP works out the running cost from your ZIP, using the 3,531 kWh of electricity at the medium draw pattern. On the same tariff, a model below the class median of 3,531 kWh would use less electricity than this one. How much that saves depends on your rate, so it is unknown here. The running cost for a household that draws more or less than the test day is also not available. The installed price appears in its own block on this page, with its source and date. That block gives a modeled installed-cost range, not a quote.
