STATE ENJB-40W 1**

This site computed the figure of 2,466 kWh; the registry does not publish it. The calculation combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.91 with the daily hot-water draw the DOE test assigns to the low draw pattern. The source is the DOE CCD, retrieved 2026-09-19. Among the 163 models registered as an electric tank at this draw pattern, this unit ranks 88th lowest for energy use. That places it in the second-highest quarter of its class, 27 kWh above the class median of 2,439 kWh. The calculation method is documented separately.

The figure fits a one- or two-person household, because it was computed only for the low draw pattern. The unit has a rated volume of 35 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 38 gallons. A household whose hot-water use is larger than the low draw pattern is outside what 2,466 kWh describes, and this page gives no estimate for that case. Readers who need a different fuel, space or size can start from the water heater selector. The data here does not say how ENJB-40W 1** performs outside the federal test's daily draw.

The running cost is not stated in the text, because it depends on your own utility electricity tariff. Multiplying 2,466 kWh by your rate gives the yearly electricity cost at the test's draw, and the cost calculator does this from your ZIP. Against a median unit in the class, the difference is 27 kWh a year, priced at the same rate. An installed price range is not published for ENJB-40W 1**. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. To compare within the same class, you can find a same-class replacement by model number.
