STATE ENJB-40 1**
0.94 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 ENJB-40 1**, an electric tank, it uses 3,456 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 75 kWh below the class median of 3,531 kWh, ranking 137th lowest of 426 comparable models.
Energy use per year
3,456 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 137 of 426, lowest energy first.
Solid line: this model (3,456 kWh). Dashed line: the class median.

The registry does not list the 3,456 kWh figure. This site calculated it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used. The second is the DOE test's daily hot-water draw for the medium draw pattern. This model's UEF is 0.94, taken from the DOE CCD and retrieved 2026-09-19. The result holds only at the federal test's daily draw. It describes a test condition, not metered use in a particular home. A different daily draw would give a different annual figure, and this page does not calculate one. The conversion steps are set out in how the annual cost is calculated.
DOE uses the medium draw pattern to represent a typical household's daily hot-water use. The ENJB-40 1** has a rated volume of 35 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons. That lets you compare like with like for a home whose peak-hour need fits within 57 gallons. The class for this comparison is the 426 electric tanks registered at the medium draw pattern. Within that class, this model's annual use is 75 kWh below the median. To check other models in the same class by model number, use find a same-class replacement.
The class comparison does not apply to homes whose daily use is above the medium draw pattern. For those homes, the 137th ranking describes a test condition the home does not match. This page has no energy figure for this model at any other draw pattern, so that value is not available. The running cost is also not stated here. It depends on your own utility's electricity rate applied to the annual figure above. The page calculates it from your ZIP in the cost calculator for your own ZIP. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote.
