STATE HESF-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 HESF-40 1**, an electric tank water heater, it 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. It equals the 3,531 kWh median of the 426 electric tank models at that pattern.
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, not taken from the registry. It uses two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. The second is the DOE test's daily hot-water draw for the medium pattern. The UEF comes from the DOE CCD, retrieved 2026-09-19. Among the 426 electric tank models at the medium draw pattern, this model ranks 213th lowest in energy use. Its difference from the class median is 0 kWh, so it sits at the middle of its class. The steps behind the figure are set out in how the annual cost is calculated.
The medium draw pattern stands for a typical mid-size household with a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. Its rated volume is 37 gallons. The 3,531 kWh figure assumes the medium pattern's daily draw. It applies to a household that uses about that much hot water. It does not apply to a household that draws more in its peak hour or much less over a day. That household's actual use is not available here. To compare units by fuel, space and size, see the water heater selector. To find a unit in the same class by model number, use the same-class replacement search.
Running cost is not stated in this text because it depends on your own utility's electricity tariff. The cost calculator for your ZIP applies your local rate to the 3,531 kWh figure. This model's energy use equals the 3,531 kWh class median. At the medium pattern and on the same tariff, its running cost therefore matches that of a median model in its class. Installed price appears in its own block on this page, with its source and date. That block shows a modeled installed-cost range, not a quote. How much electricity this unit uses in a specific home is unknown. The 3,531 kWh figure holds only at the federal test's daily hot-water draw.
