STATE PESX-40 1**

This site calculated the 3,531 kWh figure; the registry does not publish it. The calculation starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. That value is applied to the DOE test's daily hot-water draw for the medium draw pattern. The inputs come from the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw, so a home that uses a different amount of hot water each day will see a different total. The comparison class is the 426 models registered as an electric tank at the medium draw pattern. This unit ranks 213th lowest of 426 for energy use, in the second-lowest quarter of its class. The page on how the annual cost is calculated sets out each step.

The 3,531 kWh figure describes a home whose daily hot-water use matches the medium draw pattern. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 66 gallons. Its rated volume is 37 gallons. If a home's morning peak goes above 66 gallons, it falls outside what the first hour rating covers. If a home's daily use is heavier or lighter than the medium draw pattern, its yearly total will not match 3,531 kWh. For a unit rated at a different size or fuel, the selector by fuel, space and size lists other classes. To check a like-for-like swap within this class, use the same-class replacement search by model number.

This text gives no running cost, because the cost depends on your own utility's electricity tariff. The page calculates it from your ZIP, applying your local rate to the 3,531 kWh yearly figure. The cost calculator on your own ZIP shows that result. The model's energy use differs from the class median of 3,531 kWh by 0 kWh. At any given rate, its energy cost therefore equals that of a unit at the class median. The installed price range appears in a separate block on this page, with its own source and date. That range is modeled, not a quote, and its figures are not repeated here. Any figure for your own home that is not in the registry data is not available in this text.
