FRIEDRICH PROE38 S2 RH95 B

The annual figure is computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily draw for the medium pattern. The registry lists a UEF of 0.92 for this model. The result is 3,531 kWh of electricity a year, based on DOE CCD data retrieved 2026-09-19. The page on how the annual cost is calculated gives the full method. It applies only at that test draw. A household that draws more or less hot water will use a different amount, and this page has no figure for it.

Among the 426 models registered as an electric tank at the medium draw pattern, the median is 3,531 kWh per year. This model uses 3,531 kWh, so its difference from the median is 0 kWh. Its energy use is equal to the class median. Its rank is 213th lowest energy use of 426, in the second-lowest quarter of its class for energy use. That position describes energy use at the test draw only. It says nothing about hot-water capacity. Models with a lower rank use less electricity at the same draw; models with a higher rank use more.

The model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 51 gallons. Its rated volume is 35 gallons, and both are capacity figures that do not change the 3,531 kWh estimate. The estimate suits a reader comparing electric tanks at the medium pattern, but not a household whose use differs from the test draw. The running cost depends on your own electricity rate, so no cost is stated here. Use the cost calculator on your own ZIP to see it. To compare other fuels, space and size, use the water heater selector.
