The 3,493 kWh figure is not a registry value. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the medium draw pattern. For this model the registry lists a UEF of 0.93, taken from DOE CCD data retrieved 2026-09-19. The figure holds only at that test draw. A household using more or less hot water each day will use a different amount, and this page cannot say how much. At the test draw, the model sits 38 kWh below the class median of 3,531 kWh. That places it 153rd lowest for energy use among 426 electric tank models at the medium draw pattern. The steps behind the numbers are set out in how the annual cost is calculated.

The 3,493 kWh figure fits a household whose daily hot-water use is close to the medium draw pattern. DOE uses that pattern to stand for a typical mid-sized household on a busy morning. The registry gives this model a first hour rating, the gallons of hot water available in the first hour from a full tank, of 63 gallons. Its rated volume is 45 gallons. A home that needs more than 63 gallons in its first busy hour is outside what that rating covers. The registry does not report how the model performs above or below the medium draw, so that is unknown here. To compare against other models in the same class of 426, use the same-class replacement search by model number.

This page gives no running cost in the text. The yearly cost of 3,493 kWh of electricity depends on the reader's own utility electricity tariff. The page therefore computes it from the reader's ZIP rather than estimating it here. The cost calculator for your own ZIP applies your rate to the same medium-draw figure. At any single tariff, the 38 kWh gap to the 3,531 kWh class median carries into cost in proportion to that rate. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote, and it is separate from the running-cost calculation.
