The figure of 3,531 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The methodology page explains how the annual cost is calculated from such a figure. The value holds only at that test draw. A household that draws more or less hot water than the test will use more or less electricity, and this page has no value for that case. The unit is an electric tank with a rated volume of 30 gallons, so the fuel is electricity.

Among the 426 models registered as an electric tank at the medium draw pattern, this unit ranks 213th lowest energy use of 426. That places it in the second-lowest quarter of its class. Its difference from the class median of 3,531 kWh is 0 kWh, so at this draw it uses neither more nor less energy than the median model. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 59 gallons. The figures suit a reader whose household matches the medium draw pattern. They do not describe a household with a different pattern, and energy use for other patterns is not available here. The water heater selector by fuel, space and size covers other fuels and capacities.

The running cost is not stated in the text because it depends on your own utility electricity tariff. The cost calculator on your own ZIP applies your rate to 3,531 kWh, the figure at the medium draw pattern. 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 not repeated here. If you are checking this unit against a substitute, find a same-class replacement by model number using GE30S10BAM02. A replacement in the same class is compared at the same draw pattern, so its annual energy can be read against the class median of 3,531 kWh.
