The figure of 2,439 kWh is not read from the registry directly. This site computes it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. It also uses the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity, and the DOE CCD entry was retrieved on 2026-09-19. Because the figure depends on that test draw, a household that uses more or less hot water than the test will see a different annual total. The steps of the calculation are set out in how the annual cost is calculated.

The comparison group is the 163 models registered as an electric tank at the low draw pattern. Within it, this model ranks 19th lowest energy use of 163, which places it in the lowest quarter of its class for energy use. Its 2,439 kWh equals the class median of 2,439 kWh, so the difference is 0 kWh. This page does not state how many models share the same annual figure, so that count is not available here. The comparison suits a reader checking this model against others tested at the same draw pattern. It does not describe use at any other draw pattern, and no figure for those patterns is available in this data.

Running cost is not stated in this text, because it depends on your own utility electricity tariff. The cost calculator on your own ZIP applies your rate to the 2,439 kWh figure. The installed-price block on this page is separate and is a modeled range, not a quote. For capacity, the first hour rating, the gallons of hot water available in the first hour from a full tank, is 42 gallons, and the rated volume is 30 gallons. A household whose busiest hour draws more than that first hour rating falls outside what this figure describes. If size or fuel is still undecided, the selector by fuel, space and size covers those choices.
