AMERICAN ENL-40 1**
0.89 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
AMERICAN ENL-40 1** uses 2,522 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That pattern describes a one- or two-person household. That is 83 kWh above the class median of 2,439 kWh. It ranks 143rd lowest in energy use of 163 models.
Energy use per year
2,522 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 above the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 143 of 163, lowest energy first.
Solid line: this model (2,522 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

The figure of 2,522 kWh is computed by this site, not the registry. The calculation starts from the registry's UEF, the ratio of hot water delivered to energy used. This model's UEF is 0.89. It then applies the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw, so a household using more or less hot water will see a different annual total. The class median is 2,439 kWh, and this unit sits 83 kWh above it. That places it in the highest quarter of its class for energy use, at 143rd lowest of 163.
The figure fits a reader whose household matches the low draw pattern, a one- or two-person household. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. The rated volume is 35 gallons. These are the registry's ratings for this model. For a larger household, the 2,522 kWh figure does not apply, and this page has no figure for other draw patterns. To compare fuel, space and size, use the water heater selector. To find a same-class replacement by model number, use the replacement finder.
The running cost is not stated in this text because it depends on your own utility electricity tariff. The cost calculator applies the rate for your ZIP to the 2,522 kWh figure. The method for the annual cost is described separately. At any one rate, this unit's running cost is higher than a median unit's, because its energy use is 83 kWh above 2,439 kWh. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and that range is not stretched past its limit.
