HUBBELL ME30

The registry lists a 0.92 UEF, the ratio of hot water delivered to energy used, for the HUBBELL ME30. The annual energy figure is not a registry value. This site computed 2,439 kWh from that UEF and the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure describes the test's draw only and does not predict any single household's use. Rated volume is 29 gallons, which is storage capacity and does not enter the energy calculation. The steps are set out in how the annual cost is calculated.

Among the 163 models registered as an electric tank at the low draw pattern, this model ranks 19th lowest for energy use. That places it in the lowest quarter of its class. Its 2,439 kWh equals the class median of 2,439 kWh, a difference of 0 kWh. The data here do not show how many models share that value, so both positions are reported as given. The low draw pattern corresponds to a small household. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 42 gallons. That suits a household whose use resembles the test's draw. It does not describe a household with heavier use, because energy figures for other draw patterns are not available for this model on this page.

Running cost is not stated here because it depends on the electricity rate you pay. Multiply 2,439 kWh by your own rate per kilowatt-hour to check it, or enter your ZIP in the cost calculator, which applies the utility tariff for your area. The installed price range appears in its own block on this page with its source and date, and it is a modeled range, not a quote. To compare this model with others, find a same-class replacement by model number or use the water heater selector to filter by fuel, space and size. Both 2,439 kWh and the rank of 19th lowest apply only to the low draw pattern.
