FRIEDRICH PROE55 T2 RH94

The 3,531 kWh figure is calculated by this site. The registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium draw pattern. For this model the UEF is 0.92. The underlying registry record comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at the federal test's daily draw. A household that uses more or less hot water than the test assumes will use a different amount of electricity. That amount is not available from this data. The method behind the annual figure sets out each step of the calculation.

The comparison group is the 426 models registered as an electric tank at the medium draw pattern. This model ranks 213th lowest in that group for energy use. The class median is 3,531 kWh, so this model's use differs from the middle of the class by 0 kWh. It has 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 72 gallons. That rating covers a home whose busiest hour stays within 72 gallons. A home whose peak-hour demand is higher falls outside what this rating covers. For a unit on another fuel or of another size, see the selector by fuel, space and size.

This page does not state a running cost. The cost of 3,531 kWh of electricity depends on each reader's own utility tariff. The cost calculator for your own ZIP applies your local electricity rate to this model's annual use at the medium draw pattern. The installed-price range appears in its own block on this page, with its source and date. It is a modeled range, not a quote. A plumber or seller checking a replacement can use the same-class replacement search by model number. That search compares this model's 3,531 kWh with other electric tank units at the same draw pattern. The data does not show actual energy use in any single home.
