G

Grade G: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).

This GE GE40S12BLM01 uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. The figure equals the class median of 3,531 kWh, a difference of 0 kWh, among 426 electric tank models.


Energy use per year

3,531 kWh a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.

That is equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.

What these figures mean

The annual figure of 3,531 kWh was computed by this site, not by 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. This model's UEF is 0.92. The source is the DOE CCD, retrieved 2026-09-19. The figure applies only to the medium draw pattern and to electricity. Energy use at other draw patterns is not available here, so it is not estimated. A household whose hot-water use differs from the test's daily draw will see a different result. The method is described on the methodology page.

Among the 426 models registered as an electric tank at the medium draw pattern, this one ranks 213th lowest for energy use. Its 3,531 kWh equals the class median of 3,531 kWh, so the difference is 0 kWh. That places it in the second-lowest quarter of its class for energy use. At this draw pattern, its energy use matches the median model of the group. This suits a reader who wants a unit close to the typical energy use of its class. It does not suit a reader who needs a unit ranked near the lowest of the 426. To compare against other models in the same class, use the same-class replacement finder.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons for this unit. The rated volume is 40 gallons. These are the sizing figures listed for the model. Whether they cover a given household's morning demand is not something this page can determine. Running cost depends on your own utility electricity rate, so no cost figure is written in the text. Enter your ZIP in the cost calculator to apply your rate to 3,531 kWh. To compare other fuels, sizes and spaces, use the water heater selector.
