The figure of 2,439 kWh is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity, and the value applies only at that test draw. A household that uses more or less hot water will see a different total. The source is DOE CCD, retrieved 2026-09-19. Because the figure comes from a test condition, it is a basis for comparing models and not a prediction of any one home's consumption. This page has no metered value for this unit.

Among the 163 electric tank models registered at the low draw pattern, this model ranks 19th lowest energy use of 163. That places it in the lowest quarter of its class for energy use. Its 2,439 kWh sits 0 kWh from the class median of 2,439 kWh, so the difference from the median is nil. The data on this page does not show how many models share this exact value, and it does not explain how that tie relates to the rank. To compare this model with others of the same class, find a same-class replacement by model number. Only models in the same class and at the same draw pattern are comparable with the 2,439 kWh figure.

The figure suits a reader whose hot-water use matches the low draw pattern, which describes a small household. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 44 gallons, and the rated volume is 27 gallons. A household with heavier use falls outside the condition behind 2,439 kWh, and this page gives no figure for other draw patterns. The running cost is not stated in the text because it depends on your own utility electricity tariff. Use the cost calculator on your own ZIP to compute it, and read how the annual cost is calculated for the method. If fuel, space or size is still open, the water heater selector covers those.
