STATE ENLB-40W 1**

The figure of 2,494 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.9 with the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The fuel is electricity, so the figure is in kilowatt-hours. It applies only at the test draw. A household that uses more or less hot water than the test assumes will see a different total, and this page does not estimate one. The steps of the calculation are set out in how the annual cost is calculated.

Among the 163 models registered as an electric tank at the low draw pattern, this one ranks 122nd lowest energy use. That places it in the second-highest quarter of its class for energy use. Its 2,494 kWh is 55 kWh above the class median of 2,439 kWh. The unit has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 38 gallons, and a rated volume of 35 gallons. The low draw pattern represents a one- or two-person household, so the figure is most relevant to readers whose use matches it. A household with heavier hot-water use is outside that pattern, and the data here does not show how this model would perform for it. A selector by fuel, space and size can narrow other options.

The running cost is not stated in the text because it depends on your own utility electricity rate. The same 2,494 kWh costs different amounts under different tariffs, so the cost calculator on your own ZIP works it out for you. No installed price range is published for this model. Its ratings, 38 gallons of first hour rating and 35 gallons of rated volume, lie outside the range the cost database's model was fitted on, and the range is not stretched past it. To compare against a unit in the same class, you can find a same-class replacement by model number, starting from ENLB-40W 1**.
