This site calculates the 3,493 kWh figure; the registry does not publish it. The figure combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium pattern. The registry lists this unit's UEF as 0.93. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The figure applies only at the federal test's daily draw, and your household may use more or less hot water. The registry does not provide your actual consumption. The steps behind the figure are set out in how the annual energy and cost figures are calculated.

The medium draw pattern represents a typical mid-sized household on a busy morning. This unit's first hour rating, the gallons of hot water available in the first hour from a full tank, is 56 gallons. Its rated volume is 36 gallons. It ranks 153rd lowest for energy use among the 426 electric tank models registered at the medium pattern. The figure describes a household whose demand matches that pattern. A household that regularly uses more hot water than the pattern assumes falls outside the test condition, and the registry gives no figure for that case. To compare other units, use the water heater selector by fuel, space and size, or find a same-class replacement by model number.

Running cost is not given in this text because it depends on your utility's electricity tariff. The page calculates it from your ZIP by pricing the 3,493 kWh at the medium pattern at your local rate. The 38 kWh gap to the class median of 3,531 kWh only becomes a cost once that rate is applied. Until then, its effect on your bill is unknown. You can run the same figure in the cost calculator for your own ZIP. The installed price range appears in its own block with its source and date. It is a modeled range, not a quote from an installer.
