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 this unit's listing? The STATE 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 is 83 kWh above the class median of 2,439 kWh, and it ranks 143rd lowest 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 a computed value, not a registry entry. This site started from the registry's UEF, the ratio of hot water delivered to energy used. It combined that value with the DOE test's daily hot-water draw for the low draw pattern. The model's UEF is 0.89 at that draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies to a one- or two-person household drawing the test's daily volume. A household drawing more or less hot water will see a different total. The annual cost calculation method is documented separately.
Among the 163 models registered as electric tanks at the low draw pattern, this one ranks 143rd lowest for energy use. Its 2,522 kWh sits 83 kWh above the class median of 2,439 kWh. That puts it in the highest quarter of its class for energy use. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. Its rated volume is 35 gallons. Those two ratings describe capacity, not energy use. This page draws no conclusion from them about the gap to the median.
The figure fits a one- or two-person household, because that is the draw pattern it was computed for. Energy use at any other draw pattern is not available for this model. A reader who puts low energy use first will find most of the class ahead of it, at 143rd lowest of 163. Running cost depends on your own electricity rate, so no amount is stated here. The cost calculator for your own ZIP works it out from the 2,522 kWh at the low draw pattern. An installed price range is not published. This model's ratings lie outside the range the cost database was fitted on, and that range is not stretched. To compare other options, try the replacement finder by model number or the water heater selector by fuel, space and size.
