The registry lists a UEF, the ratio of hot water delivered to energy used, of 4.95 for this model. This site combined that UEF with the DOE test's daily hot-water draw for the high draw pattern to reach 1,002 kWh of electricity a year. The registry does not publish that annual figure itself. The site computed it from DOE CCD data retrieved 2026-09-19. The result sits 304 kWh below the class median of 1,306 kWh. A rank of 1st lowest of 194 places the model in the lowest quarter of its class for energy use. The steps behind the calculation are set out under how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the registry gives this model a first hour rating, the gallons of hot water available in the first hour from a full tank, of 133 gallons, with a rated volume of 99 gallons. Whether those ratings cover a particular home's busiest hour is for the reader to check against actual use. The 1,002 kWh figure applies only at the high draw pattern. For a household with lower hot-water use, the annual energy at its own draw is not available on this page. The water heater selector by fuel, space and size covers other cases.

The running cost is not stated here because it depends on the reader's own utility electricity tariff. Multiplying 1,002 kWh by the local rate per kilowatt-hour gives the yearly cost at the federal test's draw, and the cost calculator on your own ZIP does this automatically. The 304 kWh gap to the class median of 1,306 kWh scales with the same rate, so its cost effect differs by address. An installed price range is not published for this model: its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it.
