AMERICAN ENL-36 2**

The annual figure of 3,531 kWh is not a registry entry. 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, and the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies to a home only when its actual hot-water use matches that test draw. Inlet water temperature and standby conditions in a real home can differ, and this data does not measure them. The method behind the annual cost calculation is documented separately.

Among the 426 electric tank models registered at the medium draw pattern, this model ranks 213th lowest for energy use. That places it in the second-lowest quarter of its class. Its 3,531 kWh equals the class median of 3,531 kWh, so the difference is 0 kWh. The comparison covers energy use at this draw pattern only. It says nothing about other draw patterns or about other fuels and heater types. The registry also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 51 gallons, and a rated volume of 33 gallons. Those two values describe capacity, not energy use, and they do not change the rank.

This model fits a household close to the medium draw pattern that accepts energy use at the class median of 3,531 kWh. It fits less well where peak-hour demand exceeds the first hour rating of 51 gallons, or where the household's daily use differs from the test draw behind 3,531 kWh. The running cost is not stated in this text, because it depends on your own electricity rate applied to those 3,531 kWh. The cost calculator on your own ZIP applies your local tariff.
