GE GE50S10BAM02

The 3,531 kWh figure is computed by this site, not taken directly from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium pattern. For the GE50S10BAM02, the UEF is 0.92, and the fuel is electricity. The registry source is DOE CCD, retrieved 2026-09-19; the steps are set out in how the annual energy and running cost are calculated. Among the 426 electric tank models at the medium draw pattern, this unit ranks 213th lowest in energy use. A household that draws more or less hot water than the test will use a different amount. That amount is not available here, because the registry reports only the test condition.

The medium draw pattern describes a typical household's daily hot-water use, including a busy morning. This tank has a rated volume of 50 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 74 gallons. That figure is the one to check against a home's busiest hour of use. A home whose busiest hour needs more than 74 gallons falls outside what this rating covers. Figures for this model at other draw patterns are not available on this page. To compare other units, use the water heater selector by fuel, space and size. A plumber or seller checking a swap can also find a same-class replacement by model number.

The running cost is not stated in this text. It depends on the reader's own utility electricity tariff, applied to the 3,531 kWh test-draw figure. The cost calculator on your own ZIP computes it from that tariff. At any single rate, this model's running cost at the medium draw pattern would match a model at the class median of 3,531 kWh, since the difference is 0 kWh. Actual bills also depend on how far a household's use departs from the test draw, which is not known here. The installed price shown in its own block is a modeled installed-cost range with its source and date, not a quote. This page does not restate it.
