STATE ENL-36 2**

The registry does not print the 3,531 kWh figure. This site calculated it from two inputs. The first is the model's UEF, the ratio of hot water delivered to energy used, listed at 0.92. The second is the DOE test's daily hot-water draw for the medium pattern. The source is the DOE CCD, retrieved 2026-09-19. The result applies only at that test draw. Among the 426 models registered as an electric tank at the medium draw pattern, the median is also 3,531 kWh. This model ranks 213th for lowest energy use out of 426. That places it in the second-lowest quarter of its class. The steps behind the calculation are set out in how this site calculates annual energy and cost.

The medium draw pattern describes a typical three- or four-person household. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. Its rated volume is 33 gallons. A household whose peak hour needs more than 51 gallons falls outside what this rating covers. The registry data on this page gives no energy figure for other draw patterns, so that value is not available here. If your household needs a different fuel or size, the water heater selector by fuel, space and size filters on those inputs. To compare this unit with another model in the same class, use the same-class replacement search by model number.

This text does not state a running cost. The cost depends on your own utility's electricity tariff, applied to the 3,531 kWh this model uses at the medium draw pattern. The page calculates that cost from your ZIP, so this text gives no single figure. You can run it in the running cost calculator for your ZIP. This model's energy use equals the class median, a difference of 0 kWh. On any given tariff, its running cost therefore matches that of a model at the class median. The installed price range appears in its own block on this page, with its source and date. That block shows a modeled installed-cost range, not a quote.
