0.91 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).
For STATE ENJ-30 1**, the federal test gives 2,466 kWh of electricity a year. That is at the low draw pattern, the standard daily hot-water usage DOE tests against, meant for a one- or two-person household. It sits 27 kWh above the class median of 2,439 kWh among 163 electric tanks.
Energy use per year
2,466 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 88 of 163, lowest energy first.
Solid line: this model (2,466 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 2,466 kWh is not a registry value. This site computed it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.91 for this model. The second is the daily hot-water draw the DOE test uses for the low draw pattern. The result applies only to that test draw, and actual use in a home changes with the hot water drawn. The gap of 27 kWh above the class median of 2,439 kWh is measured under the same condition. The energy source is DOE CCD, retrieved 2026-09-19. How the annual cost is calculated is set out on the methodology page.
Within its class, this model ranks 88th lowest in energy use of 163, in the second-highest quarter for energy use. The rank compares only electric tanks registered at the low draw pattern. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 43 gallons. The rated volume is 26 gallons. The low draw pattern, a one- or two-person household, is the one this model is listed under. A household that draws more hot water than that test assumes can use more energy than the figure shows. The data here does not show performance at other draw patterns. For other fuels or sizes, use the water heater selector by fuel, space and size.
The running cost is not stated in the text. It depends on your own utility electricity tariff and scales with 2,466 kWh. The cost calculator on your own ZIP applies your rate to that figure. An installed price range is not published for STATE ENJ-30 1**. Its ratings, a first hour rating of 43 gallons and a rated volume of 26 gallons, lie outside the range the cost database's model was fitted on. That range is not stretched past its limit. The 27 kWh difference from the class median describes energy only, not cost. To compare against another unit, find a same-class replacement by model number.
