GE GE40S08DAT02
0.92 UEF DOE CCD · 2026-09-19Grade 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).
If you are checking the GE GE40S08DAT02, it uses 3,531 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 0 kWh from the class median of 3,531 kWh, so it equals that median. Among electric tank models, it ranks 213th lowest of 426.
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.
Solid line: this model (3,531 kWh). Dashed line: the class median.

UEF 0.92 · Grade G Price it on your ZIP
The 3,531 kWh figure is computed by this site, not taken 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 draw pattern. For the GE40S08DAT02, the UEF is 0.92. The result is electricity only, because this unit is an electric tank. It holds only at the federal test's daily draw. A household that draws more or less hot water each day will use a different amount, and this page cannot say how much. The registry value comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The steps behind the calculation are set out in how the annual cost is calculated.
The GE40S08DAT02 is compared with the 426 models registered as an electric tank at the medium draw pattern. It ranks 213th lowest for energy use in that group. Its 3,531 kWh matches the class median of 3,531 kWh, a difference of 0 kWh. At the same test draw, any same-class model listed below that median uses less electricity, and any listed above it uses more. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. That comes from a rated volume of 40 gallons. A home whose peak-hour demand exceeds 55 gallons needs more than this rating covers. To check other models in the same class, use find a same-class replacement by model number.
This text states no running cost for the GE40S08DAT02. The cost of 3,531 kWh a year depends on the reader's own utility electricity tariff. Tariffs differ by utility and by rate plan, so any single figure written here would be wrong for most readers. Instead, the page computes it from your ZIP in the cost calculator on your own ZIP. That result carries the same condition as the energy figure: the medium draw pattern at the federal test's daily draw. The modeled installed-cost range appears in its own block, with its source and date; it is a modeled range, not a quote. Two things are not available here: this model's energy use at other draw patterns, and its measured use in any real home.
