AMERICAN 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).
Verifying this unit: the AMERICAN HESF-40 1**, an electric tank, uses 3,531 kWh 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 (difference 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.

This site computed the 3,531 kWh figure; the registry does not publish it. It combines the registry's UEF, 0.92, with the DOE test's daily hot-water draw for the medium pattern. UEF, the ratio of hot water delivered to energy used, is the only efficiency input. The data comes from DOE CCD, retrieved 2026-09-19. Against the 426 electric tanks registered at this draw pattern, the model sits 0 kWh from the class median of 3,531 kWh. That places it 213th lowest, in the second-lowest quarter for energy use. The calculation is described on the methodology page for water heaters.
The figure fits a household whose hot-water use matches the medium draw pattern, meaning a typical household on a busy morning. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. The rated volume is 37 gallons. Households that use more hot water than this pattern assumes are not covered by the 3,531 kWh figure. Their real consumption would differ, and this page has no value for it. The registry data also says nothing about other draw patterns for this model. To compare by fuel, space and size, use the water heater selector.
The running cost is not written in this text because it depends on your own electricity rate. The page multiplies 3,531 kWh by the tariff for your ZIP, so the result applies only to that rate and that draw pattern. You can run it in the cost calculator for your ZIP. The modeled installed-cost range appears in its own block with its source and date, and it is not a quote. If you need a unit in the same class as the AMERICAN HESF-40 1**, the same-class replacement finder searches by model number. Actual use in a home may differ from the test's daily draw, and this page cannot estimate that difference.
