STATE ENS-40 1**
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 ENS-40 1** against the registry, this electric tank uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 3,531 kWh, a difference of 0 kWh, and ranks 213th lowest of 426.
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 computed by this site, not published by the registry. It combines this model's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw set by DOE's test for the medium draw pattern. The UEF for the STATE ENS-40 1** is 0.92. Both inputs come from the DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw, and this page has no value for other levels of daily use. The conversion steps are listed under how the annual cost is calculated. Among the 426 electric tanks registered at the medium draw pattern, this energy use places the model in the second-lowest quarter of its class.
The medium draw pattern stands for a typical mid-size household's daily hot-water use, with a busy morning peak. This model's rated volume is 37 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. The class comparison applies to readers whose use matches that medium pattern. For a household whose daily use is heavier or lighter, the 3,531 kWh figure is not the right reference. This page has no figure for this model at any other draw pattern, so that energy use is not available here. You can filter models registered at other patterns, fuels and sizes in the selector by fuel, space and size.
This text does not turn the 3,531 kWh of electricity a year into a running cost. That cost depends on your own utility's electricity tariff. The page computes it from your ZIP, and the cost calculator on your own ZIP uses the same method. This model's energy use equals the class median of 3,531 kWh, a difference of 0 kWh. A model at the class median would therefore give the same energy result at the test draw. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote. To check a same-class unit by model number, use find a same-class replacement.
