ARISTON EVR052*2X***

The 3,493 kWh figure does not come from the registry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used. It combined that ratio with the DOE test's daily hot-water draw for the medium draw pattern. For the EVR052*2X***, the UEF is 0.93 and the rated volume is 48 gallons. The inputs come from the DOE CCD, retrieved 2026-09-19. The medium pattern represents a typical mid-sized household with a busy morning. A home that draws more or less hot water than the test assumes will use a different amount of electricity. This data does not show how large that difference would be for any given home. The calculation steps are set out in how the annual cost is calculated.

Its class is the 426 models registered as an electric tank at the medium draw pattern. Among them, this model ranks 153rd lowest in energy use. The class median is 3,531 kWh a year, and this model sits 38 kWh below it. A rank of 153rd also means other models in the class use less energy. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. These figures describe a household whose morning demand matches the medium pattern and stays within that rating. A household that needs more than 62 gallons in the first hour falls outside what these figures describe.

This text does not state the running cost of 3,493 kWh a year. That cost depends on your own utility's electricity tariff. The page computes it from your ZIP in the running-cost calculator for your ZIP. Your tariff also sets what the 38 kWh gap from the class median is worth. The installed price range appears on this page in its own block, with its source and date. It is a modeled installed-cost range, not a quote. If the EVR052*2X*** does not fit your fuel, space or size, the water heater selector by fuel, space and size lists other models.
