FRIEDRICH XE55T12CS55U0

The registry lists this unit with a UEF, the ratio of hot water delivered to energy used, of 0.92. The registry does not publish an annual energy figure, so this site computed 3,531 kWh from that UEF and the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19, and the figure covers electricity only. The class is the 426 models registered as an electric tank at the medium draw pattern. Its median is 3,531 kWh, so this unit differs from it by 0 kWh. It has the 213th lowest energy use of 426, which places it in the second-lowest quarter of its class. The calculation method explains how the figure is derived.

The listing gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 74 gallons, and a rated volume of 55 gallons. The medium draw pattern represents a typical household on a busy morning. A household whose use resembles that pattern can compare 3,531 kWh directly with the other 426 models in the class. A household that uses noticeably more or less hot water than the test assumes will see a different yearly figure, and this page has no value for other draw patterns. The rank of 213th lowest concerns energy use only; it does not measure whether the tank meets peak demand. The water heater selector filters by fuel, space and size.

Running cost is not written here because it depends on your own utility electricity rate, and this page does not estimate it. The calculation multiplies 3,531 kWh by that rate, and the cost calculator does this from your ZIP. At the same rate, a model at the class median of 3,531 kWh would cost the same to run, since the difference is 0 kWh. The energy figure assumes the medium draw pattern, so actual use in a home can differ from the test's daily draw. The installed price range appears in its own block with its source and date, as a modeled range and not a quote. To look for a same-class alternative, search by model number using XE55T12CS55U0.
