ARISTON ELV055*2*****

The 5,278 kWh figure is not a registry value. This site computed it from the registry's UEF and the daily hot-water draw that the DOE test assigns to the high draw pattern. UEF, the ratio of hot water delivered to energy used, is 0.94 for this model. The energy source is DOE CCD, retrieved 2026-09-19, and the fuel is electricity. Actual use in a home depends on how much hot water the household draws, and that is not available here. The method is set out in how the annual cost is calculated. Read the figure as a comparison at the test's draw, not as a forecast for one house.

The ARISTON ELV055*2***** is an electric tank with a rated volume of 55 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 77 gallons. These are the figures to compare with a household's peak demand. On energy use, the model sits 3,972 kWh above the class median of 1,306 kWh. It ranks 172nd lowest of 194 models, which places it in the highest quarter of its class for energy use. A reader whose main concern is low annual energy among electric tanks at this draw pattern should weigh that position. Other fuels and sizes can be checked with the water heater selector.

The running cost is not written here because it depends on the utility electricity tariff at the reader's own address. The arithmetic is 5,278 kWh at the high draw pattern multiplied by the reader's rate per kWh. The cost calculator does this from a ZIP code. The same rate applies to the 3,972 kWh gap from the class median of 1,306 kWh, so the cost of that gap can be worked out the same way. The installed price range appears in its own block with its source and date, and it is not restated in this text. To look for a unit in the same class, use the replacement finder by model number. Whether 5,278 kWh matches a particular home is unknown from registry data.
