AMERICAN ENS-30 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).
Checking the AMERICAN ENS-30 1**, an electric tank? At the low draw pattern, the standard daily hot-water usage DOE tests against, it uses 2,522 kWh of electricity a year. That is 83 kWh above the class median of 2,439 kWh across 163 models, ranked 143rd lowest in energy use of 163.
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 annual figure of 2,522 kWh is computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.89 for this model, with the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. Among the 163 models registered as an electric tank at this draw pattern, the class median is 2,439 kWh. This model sits 83 kWh above it, at 143rd lowest energy use of 163, which is the highest quarter of its class for energy use. The calculation steps are set out under how the annual cost is calculated.
The rated volume is 27 gallons, and the first hour rating, the gallons of hot water available in the first hour from a full tank, is 47 gallons. The energy figure belongs to the low draw pattern, a one- or two-person household. For that household, 2,522 kWh is the test-based figure. A household that draws more hot water than the federal test's daily draw is not covered by this figure, and this page has no value for it. The figure also does not show how the tank performs in a specific home, because only the federal test conditions are used. To compare other fuels, spaces or sizes, use the water heater selector by fuel, space and size.
The running cost is not stated here because it depends on your own utility electricity tariff. The cost calculator on your own ZIP applies your rate to the 2,522 kWh figure at the low draw pattern. Any cost derived this way carries the same condition: it holds only at the federal test's daily draw. The installed price range is not published for this model. Its ratings, including the 47-gallon first hour rating and the 27-gallon rated volume, lie outside the range the cost database's model was fitted on, and the range is not stretched past it. If you need a same-class unit, you can find a replacement by model number starting from ENS-30 1**.
