FRIEDRICH XE50T12CS55U1

This site computed the annual figure of 3,531 kWh; the registry does not publish it. The calculation combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw for the medium draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure applies only to that test draw and to electricity as the fuel, so a household that uses more or less hot water than the test assumes will see a different result. The registry gives no value for those cases, and this page does not estimate one. The steps are set out in how the annual cost is calculated.

Against the 426 electric tank models registered at the medium draw pattern, this unit ranks 213th lowest for energy use. Its 3,531 kWh differs from the class median of 3,531 kWh by 0 kWh, which places it in the second-lowest quarter of its class. On energy use alone, the data show it neither above nor below a typical model in this class. For sizing, the first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons, and the rated volume is 45 gallons. These figures suit a check for a household whose busy-morning demand matches the medium draw pattern. They do not show how the unit performs under heavier peak demand; the selector by fuel, space and size can narrow that question.

The running cost is not stated here because it depends on your own utility electricity tariff. The energy figure of 3,531 kWh is the fixed part; the rate you pay per kilowatt-hour is the part that varies by address. The cost calculator on your own ZIP applies your local rate to this model's figure at the medium draw pattern. The result carries the same condition as the energy figure: the federal test's daily hot-water draw. The installed price appears in a separate block with its source and date, as a modeled range and not a quote.
