STATE HETF-55 1**

The figure of 5,278 kWh is not a registry entry. This site computed it, not the registry. It used the registry's UEF, the ratio of hot water delivered to energy used. For this model the UEF is 0.94. The other input is the DOE test's daily hot-water draw for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. The value holds only at that test draw. A household that uses more or less hot water will use a different amount of electricity, and this page has no value for that case. The method is described in how the annual cost is calculated.

Among the 194 models registered as an electric tank at the high draw pattern, this model's rank is 172nd lowest energy use of 194. That places it in the highest quarter of its class for energy use. Its 5,278 kWh is 3,972 kWh above the class median of 1,306 kWh, so most models in the class use less electricity at the same test draw. The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 75 gallons, and a rated volume of 55 gallons. This page does not judge whether those values meet a given household's demand. For a reader comparing on energy use alone, the rank is the relevant fact, and a same-class replacement can be looked up by model number.

Running cost is not written here because it depends on your own utility electricity rate, which varies by location. Multiplying 5,278 kWh by your rate per kilowatt-hour gives the yearly cost at the test draw. The cost calculator does this from your ZIP code. A modeled installed-cost range appears in its own block on the page, with its source and date. It is not a quote, and its figures are not repeated here. The energy figure is test-based and is not a measurement of an installed unit; metered use in a home is not available in the data. For other fuels, sizes or space limits, the water heater selector covers them.
