GE GE40T08DAT02

This site calculated the 3,531 kWh figure; the registry does not publish it. We used the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. We combined it with the DOE test's daily hot-water draw for the medium pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw. A household that uses more hot water each day than the medium pattern assumes would use more electricity than 3,531 kWh. A household that uses less would use less. The registry does not give a figure for any other daily draw, so it is not available here. The steps are set out in how the annual cost is calculated.

The GE40T08DAT02 has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 58 gallons. Its rated volume is 40 gallons. The medium pattern stands for a typical mid-sized household with a busy morning. Because its energy use equals the class median, this model uses neither more nor less electricity than the median model in its class at that draw. A home that needs more than 58 gallons in its busiest hour needs more than this rating covers. The registry does not report how the unit performs outside the test conditions, so that is unknown. For a different fuel or tank size, the selector by fuel, space and size filters the registry.

The running cost is not stated in this text. It depends on the electricity tariff from your own utility, which this page does not know in advance. The cost calculator for your own ZIP applies your local rate to the 3,531 kWh figure. Until you enter a ZIP, this page does not know what any single home pays a year. The installed price range appears in its own block with its source and date. It is a modeled range, not a quote. If you are matching a replacement, the same-class replacement finder by model number lists the 426 electric tank models registered at the medium draw pattern.
