Rheem PROE30 T2 RH95

The registry does not state 2,439 kWh; this site computes it. The inputs are the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the low draw pattern. The UEF for this model is 0.92. The fuel is electricity, so the result is in kilowatt-hours a year. The source is DOE CCD, retrieved 2026-09-19. The method behind the annual figure is documented separately. A household whose real hot-water use differs from the federal test's daily draw will use a different amount, and this page does not estimate it.

Among the 163 models registered as an electric tank at the low draw pattern, this unit has the 19th lowest energy use. That puts it in the lowest quarter of its class. Its 2,439 kWh equals the class median of 2,439 kWh, so the difference is 0 kWh. The count of models that share this exact figure is not available on this page. The comparison holds only for electric tanks at the low draw pattern and says nothing about other fuels or draw patterns. It also does not measure how much hot water a particular household uses.

The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank. For this model it is 44 gallons, with a rated volume of 27 gallons. The 2,439 kWh figure applies to a one- or two-person household at the low draw pattern. A larger household, or one with heavier use, falls outside the condition that figure depends on, and this page gives no figure for it. Use the water heater selector to compare by fuel, space and size. The running cost is not written here because it depends on your own utility electricity tariff. Enter your ZIP in the cost calculator to apply your rate to 2,439 kWh. The modeled installed-cost range appears in its own block on this page, with its source and date.
