The registry does not publish the 3,531 kWh figure. This site calculates 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. The UEF for this model is 0.92. The source is the DOE CCD, retrieved 2026-09-19. The figure describes the federal test condition, not energy measured in a real household. It does not describe a home whose daily hot-water draw is different from the test's draw. The methodology page shows how the annual energy and cost figures are calculated step by step.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons for this model. The rated volume is 45 gallons. The medium draw pattern represents a typical household's daily use, including a busy morning. A household that needs more than 63 gallons in its busiest hour is outside what this rating covers. The class is the 426 medium-draw electric tanks. This model's 3,531 kWh equals the class median, so its energy use is neither above nor below that midpoint. If you want a unit in the same class, you can find a same-class replacement by model number. To look at other fuels or tank sizes, use the water heater selector by fuel, space and size.

This text does not state the running cost because it depends on your own utility's electricity tariff. After you enter your ZIP, the page applies your tariff to the 3,531 kWh figure. No cost is estimated here. You can also do this in the water heater cost calculator for your ZIP. The installed price range is shown in its own block, with its source and date. It is a modeled installed-cost range, not a quote. This page cannot show how much energy the model uses in a specific home. The registry data does not include a home's actual hot-water draw, so actual electricity use is not available.
