U.S. CRAFTMASTER ENL-50 1**

The registry does not list 3,531 kWh itself. This site calculated it from the model's UEF, the ratio of hot water delivered to energy used. It also used the DOE test's daily hot-water draw for the medium pattern. The registered UEF is 0.92, from the DOE CCD, retrieved 2026-09-19. Among the 426 electric tanks at the medium draw pattern, this model ranks 213th lowest for energy use. The figure holds only at the test's daily draw. The registry gives no energy figure for other usage levels, so none is stated here. The steps from registry data to a yearly figure are set out in how the annual cost is calculated.

The medium draw pattern stands for a typical household's hot-water use on a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. Its rated volume is 48 gallons. A plumber or seller matching an existing unit can check these two figures against the old tank's label. To check against other models in the same class, use a same-class replacement search by model number. The registry does not record service life or performance outside the test. That information is not available on this page.

A household whose morning demand regularly goes beyond the medium pattern is outside the condition behind 3,531 kWh. The registry states no figure for heavier use at this model's 51 gallon first hour rating. Readers comparing other fuels or tank sizes can use the selector by fuel, space and size. The running cost is not given in this text. It depends on your own utility's electricity tariff. The cost calculator on your own ZIP applies your local rate to 3,531 kWh. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote.
