U.S. CRAFTMASTER ENS-50 1**

The 3,531 kWh figure is not printed in the registry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. That ratio is combined with the daily hot-water draw the DOE test sets for the medium draw pattern. The registry data comes from the DOE CCD, retrieved 2026-09-19. Among the 426 models registered as an electric tank at the same draw pattern, the class median is 3,531 kWh. This model is equal to that median, with a difference of 0 kWh. The figure holds only at the test's daily draw. A home that uses more or less hot water will have a different annual total, and that total is not available here.

DOE uses the medium draw pattern to represent a typical household of several people. For this model, the first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons. Its rated volume is 46 gallons. A plumber or seller checking a match for a home with medium daily use can compare those two figures with the old unit's label. A home with heavier morning demand than the medium pattern assumes falls outside what the 3,531 kWh figure describes. Energy figures for this model at other draw patterns are not available on this page. To compare other sizes or fuels, use the water heater selector by fuel, space and size. You can also find a same-class replacement by model number.

Running cost is not stated in this text. It is the 3,531 kWh of electricity a year multiplied by your own utility tariff, so no single figure fits every reader. The page works it out from your ZIP in the cost calculator for your own ZIP. The steps behind that result are set out in how the annual cost is calculated. This model's use equals the class median of 3,531 kWh. So, at the same draw and on the same rate, its computed cost matches that of a median model in its class. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
