STATE ENT-50-1**

This site computes the 3,531 kWh figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. For this model the UEF is 0.92, and together with the draw it sets the annual figure. The medium draw pattern stands for typical household hot-water use on a busy morning. A household drawing more hot water than the test assumes would use more electricity than 3,531 kWh a year. A household drawing less would use less, but this page does not model either case. The source is the DOE CCD, retrieved 2026-09-19. The steps are set out in how the annual cost is calculated.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons here. Its rated volume is 46 gallons. These two values describe what the tank can deliver, not what it uses in a year. The 3,531 kWh figure fits a household whose daily use is close to the medium draw pattern. A household with heavier morning demand falls outside that pattern, so the annual figure would understate its use. The data on this page does not say how large that gap would be. To compare other units, use the water heater selector by fuel, space and size, which filters on those criteria. For a same-class match, see the same-class replacement finder by model number.

Among the 426 electric tanks registered at the medium draw pattern, this model ranks 213th lowest in energy use. That rank places it at the median noted above. Running cost is not stated in this text because it depends on your own utility's electricity tariff. The page computes it from your ZIP in the running cost calculator for your ZIP. Whatever rate you enter, it applies to the same 3,531 kWh at the medium draw pattern. The installed price range appears in its own block, with its source and date. That range is a modeled installed-cost range, not a quote, and this text does not restate its figures.
