The 3,531 kWh figure is computed by this site, not taken from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw. The UEF comes from the DOE CCD registry, retrieved 2026-09-19. The medium pattern stands for a typical three- or four-person household. If a home draws more or less hot water than that test day, its real use will differ from 3,531 kWh. How far it would differ is not available from the registry data. Each step behind the figure is set out in the methodology for the annual energy and cost figures.

The class comparison covers the 426 models registered as an electric tank at the medium draw pattern. This model sits 0 kWh from the class median given above. Its rank of 213th lowest places it in the second-lowest quarter of its class for energy use. The tank's rated volume is 35 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 54 gallons. A home whose busiest hour needs more than 54 gallons falls outside what this rating covers. A home within that amount and near the medium pattern matches the test conditions.

This page states no running cost in the text, because the cost of 3,531 kWh depends on your own electricity tariff. Utility rates differ by provider and plan, so no single figure would hold for every reader. The page computes the cost from your ZIP instead, using the same 3,531 kWh at the medium draw pattern. Because the difference from the class median is 0 kWh, a class-median model would cost the same on the same tariff. You can run that figure in the running-cost calculator for your own ZIP. The installed price appears in its own block as a modeled range with its source and date. That range is not a quote.
