FRIEDRICH PROE28 S2 RH95

The 2,439 kWh figure starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. This site combines that UEF with the federal test's daily hot-water draw for the low draw pattern. The registry does not publish the annual figure itself. The energy data comes from DOE CCD, retrieved 2026-09-19. The result describes the test's daily draw only, so a home that draws more or less hot water than the test will use a different amount. The actual daily draw of your home is not available here. The methodology page sets out the calculation.

The class here is the 163 models registered as an electric tank at the low draw pattern. Their median is 2,439 kWh, and this model differs from it by 0 kWh. The registry comparison also ranks it 19th lowest energy use of 163, which places it in the lowest quarter of its class. The data supplied does not show why a median-equal figure and a lowest-quarter rank appear together, so both are reported as given. The rated volume is 25 gallons, and the first hour rating, the gallons of hot water available in the first hour from a full tank, is 45 gallons. A household whose peak-hour demand exceeds that rating is not served by these figures; the water heater selector filters by fuel, space and size.

The running cost is not stated in this text because it depends on your own utility electricity tariff. Multiplying 2,439 kWh by your rate gives the yearly cost for the low draw pattern, and the cost calculator does this from your ZIP. The installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it.
