AMERICAN ENT-55 1**
0.93 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 model, AMERICAN ENT-55 1** uses 3,493 kWh a year. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 38 kWh below the class median of 3,531 kWh, and it ranks 153rd lowest of 426.
Energy use per year
3,493 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 153 of 426, lowest energy first.
Solid line: this model (3,493 kWh). Dashed line: the class median.

The figure of 3,493 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for this pattern. This model's UEF is 0.93, and the source is DOE CCD, retrieved 2026-09-19. The result holds only for the medium pattern, which represents a typical household on a busy morning. This page does not show figures for other draw patterns. It describes the test conditions and does not measure use in any particular home. The method for calculating the annual cost is described in full elsewhere.
The unit is registered at the medium draw pattern, with a rated volume of 55 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 72 gallons. Its rank of 153rd lowest of 426 places it in the second-lowest quarter of its class for energy use. That suits a reader who compares models by annual energy at the medium pattern. It does not settle the question for a household whose morning demand differs from the test's draw. For that case, the water heater selector by fuel, space and size narrows the field. This page does not rate fit for any household.
Running cost is not stated in the text. It depends on your own utility electricity tariff, and this page does not estimate it. The cost calculator for your own ZIP computes it from 3,493 kWh at the medium draw pattern. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote, and it is not restated here. A household that draws more or less hot water than the test will see use that differs from 3,493 kWh. To find a same-class unit, search for a replacement by model number, starting from AMERICAN ENT-55 1**.
