AMERICAN ENT-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 this listing, the AMERICAN ENT-40 1** uses 3,531 kWh of electricity a year. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. 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 registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site derived 3,531 kWh from that UEF and the daily hot-water draw in the DOE test for the medium draw pattern. The registry does not publish the annual figure itself. The source is DOE CCD, retrieved 2026-09-19. The figure applies only at the test's daily draw. A household that uses more or less hot water will have a different annual use, and how much it differs is not available in this data. The method for the annual calculation is documented separately.
Among the 426 electric tank models at the medium draw pattern, this model ranks 213th lowest in energy use. That puts it in the second-lowest quarter of its class. Its difference from the median is 0 kWh, so it sits at the class median rather than above or below it. The rated volume is 36 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 53 gallons. The medium draw pattern describes a typical household on a busy morning. This model suits a household whose busiest-hour demand stays within that first hour rating. It suits less well a household whose busiest-hour demand exceeds 53 gallons.
The running cost is not stated here because it depends on your own utility electricity tariff. Use the cost calculator on your own ZIP to apply your rate to 3,531 kWh. The result holds only at the medium draw pattern and the test's daily draw. A separate block on this page shows a modeled installed-cost range with its source and date. That range is not a quote and is not repeated here. If you need a comparison unit, find a same-class replacement by model number so that fuel and draw pattern stay the same. The class median of 3,531 kWh is the reference point for that comparison.
