FRIEDRICH XE50M12CS55U1

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site multiplied that UEF by the daily hot-water draw the DOE test assigns to the medium draw pattern. The result is 3,531 kWh of electricity a year. The registry does not publish that annual figure itself. It is computed here from DOE CCD data retrieved on 2026-09-19. The figure holds only at the test draw. A household that uses more or less hot water than the test assumes will see a different total, and the data does not say by how much. The steps are set out in how the annual cost is calculated.

Among the 426 models registered as an electric tank at the medium draw pattern, this unit ranks 213th lowest for energy use. Its 3,531 kWh equals the class median of 3,531 kWh, a difference of 0 kWh, which places it in the second-lowest quarter of its class. The rank compares energy use at the test draw only. It says nothing about capacity. 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. The data does not show how those two values compare with the class. To check size against your space, use the selector by fuel, space and size, or find a same-class replacement by model number.

The running cost is not stated here because it depends on your own utility electricity rate. Multiplying 3,531 kWh by your rate per kWh gives the yearly cost at the medium draw pattern. The cost calculator on your own ZIP does this for you. This model suits a household whose hot-water use is close to the test draw and whose target is energy use at the class median of 3,531 kWh. It suits less well a household whose use differs widely from the test draw, because the annual figure is tied to that draw. The installed price appears in its own block as a modeled range with its source and date. It is not a quote.
