FRIEDRICH PROE36 S2 RH95
0.92 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
If you are checking the FRIEDRICH PROE36 S2 RH95, an electric tank, it uses 2,439 kWh a year at the low draw pattern. That is the standard daily hot-water usage DOE tests against, for a one- or two-person household. It equals the class median of 2,439 kWh, a difference of 0 kWh.
Energy use per year
2,439 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is equal to the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.
Solid line: this model (2,439 kWh). Dashed line: the class median.

The figure of 2,439 kWh is computed by this site, not by the registry. 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 low draw pattern. This model's UEF is 0.92. The source is DOE CCD, retrieved 2026-09-19. The model ranks 19th lowest energy use of 163 models registered as an electric tank at the low draw pattern, which is the lowest quarter of its class. Its figure equals the class median of 2,439 kWh, so the difference is 0 kWh. The supplied data do not explain how the rank and the median comparison relate. How the annual cost is calculated describes the method.
The 2,439 kWh applies only to the low draw pattern, so it fits a one- or two-person household. A household that draws more hot water than the federal test's daily draw should not read this figure as its own. Energy use at other draw patterns is not available in this data. The rated volume is 33 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 46 gallons. Those two values describe capacity, and they do not change the annual energy figure. To compare tanks by fuel, space and size, use the water heater selector.
The running cost is not stated here because it depends on your own utility electricity tariff. The 2,439 kWh is the quantity to multiply by your rate for each kilowatt-hour, and the result holds only at the low draw pattern. The cost calculator does this from your ZIP. The installed price range appears in its own block on this page, with its source and date, as a modeled installed-cost range and not a quote. This text does not repeat its figures. To look at other units in the same class as the FRIEDRICH PROE36 S2 RH95, you can find a same-class replacement by model number.
