GE GE30S12BLM01

The annual figure of 3,531 kWh is for electricity at the medium draw pattern, meaning the federal test's daily hot-water draw. This site computed it, not the registry, from the registry's UEF and that daily draw. UEF, the ratio of hot water delivered to energy used, is 0.92 for this model. The source is DOE CCD, retrieved 2026-09-19. The class median is 3,531 kWh, taken from the 426 models registered as an electric tank at the medium draw pattern. The difference from that median is 0 kWh, so this model uses the same energy as the median. Its rank is 213th lowest energy use of 426, in the second-lowest quarter of its class.

This figure suits a reader checking a household whose hot-water use resembles the medium draw pattern, because the 3,531 kWh is tied to that draw and to no other. It does not describe a household that draws more or less hot water, and a figure for other draw patterns is not available on this page. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 60 gallons. The rated volume is 30 gallons. The registry data does not show a household's own peak demand, so whether those values cover it is unknown. The water heater selector filters models by fuel, space and size.

The running cost is not written in this text, because it depends on your own utility electricity tariff. The page computes it from your ZIP, and the cost calculator applies the rate for that location to the 3,531 kWh shown here. Two households at the medium draw pattern with the same 3,531 kWh will pay different amounts if their rates differ. The steps behind the calculation are set out in the cost methodology. To compare against a same-class unit, you can find a replacement by model number starting from GE30S12BLM01. The installed price range appears in its own block, with its source and date.
