GE GE40S10BMM01

The registry lists GE GE40S10BMM01 with a UEF, the ratio of hot water delivered to energy used, of 0.92. This site combined that UEF with the DOE test's daily hot-water draw for the medium draw pattern to reach 3,531 kWh of electricity a year. The registry itself does not publish that annual figure. The source is DOE CCD, retrieved 2026-09-19. Among the 426 models registered as an electric tank at the medium draw pattern, this unit ranks 213th lowest for energy use, in the second-lowest quarter of its class. The difference from the class median of 3,531 kWh is 0 kWh. The method behind the annual figures is documented separately.

The 3,531 kWh figure applies only at the medium draw pattern. This unit has a rated volume of 40 gallons and a first hour rating, the gallons of hot water available in the first hour from a full tank, of 65 gallons. The figure describes a household whose daily hot-water use resembles the typical three- or four-person pattern. A household with heavier morning demand may see different energy use, and the registry data on this page does not say by how much. Because the difference from the median is 0 kWh, energy use alone does not separate this model from a typical one in its class. To compare by fuel, space and size, the water heater selector covers those inputs.

The running cost of 3,531 kWh depends on the electricity tariff the reader pays, so this text states no rate and no cost amount. The cost calculator applies the reader's own ZIP to this energy figure. The installed price range appears in its own block, with its source and date, as a modeled installed-cost range and not a quote. Actual household use can differ from the test's daily draw, and the registry holds no data on any individual home.
