AMERICAN ENJB-30 1**
0.9 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).
If you are verifying this model, AMERICAN ENJB-30 1**, an electric tank, uses 2,494 kWh a year at the low draw pattern, the standard daily hot-water usage DOE tests against, for a one- or two-person household. That is 55 kWh above the class median of 2,439 kWh.
Energy use per year
2,494 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 122 of 163, lowest energy first.
Solid line: this model (2,494 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 2,494 kWh is electricity use for AMERICAN ENJB-30 1** at the low draw pattern. This site computed it, not the registry. The inputs are the registry's UEF, the ratio of hot water delivered to energy used, which is 0.9 for this model, and the daily hot-water draw the DOE test assigns to this draw pattern. The DOE CCD data was retrieved 2026-09-19. The figure describes the test's standard day, so a household that draws more or less hot water than the test will use a different amount. This page gives no value for any other draw pattern. For the calculation steps, see how the annual cost is calculated.
This model ranks 122nd lowest in energy use among the 163 models registered as an electric tank at the low draw pattern. That places it in the second-highest quarter of its class for energy use. The class median is 2,439 kWh, and this model sits 55 kWh above it. Its rated volume is 26 gallons, and its first hour rating, the gallons of hot water available in the first hour from a full tank, is 47 gallons. These two ratings describe capacity and do not change the energy figure. The comparison fits a one- or two-person household, which is what the low draw pattern represents. To compare against another unit in the same class, use the same-class replacement finder by model number.
The running cost is not stated in this text because it depends on your own utility electricity tariff. Multiplying 2,494 kWh by your rate per kilowatt-hour gives a yearly cost at the low draw pattern, and the cost calculator on your own ZIP does that for you. The installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. Only the energy figure of 2,494 kWh, dated by the 2026-09-19 retrieval, is available here for AMERICAN ENJB-30 1**.
