FRIEDRICH PROE40 T2 RH95

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.93 for this model. This site combined that value with the DOE test's daily hot-water draw for the medium draw pattern to get 3,493 kWh of electricity a year. The registry itself does not publish that annual figure. The data came from the DOE CCD and was retrieved on 2026-09-19. Against the class median of 3,531 kWh, the model sits 38 kWh lower. That places it 153rd lowest energy use of 426 models and in the second-lowest quarter of its class. The steps behind the calculation are set out in how the annual cost is calculated.

This figure applies to a household that matches the medium draw pattern: a typical three- or four-person household on a busy morning. The model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 55 gallons and a rated volume of 36 gallons. A household with a larger or smaller daily draw will not use 3,493 kWh, because the figure holds only at the federal test's daily draw. The registry data gives no measured use for individual homes, so how far a given home differs is unknown. To compare other fuels, spaces and sizes, use the water heater selector.

Running cost is not stated in the text because it depends on your own electricity rate. Multiplying 3,493 kWh by the price you pay per kilowatt-hour gives the cost at the test draw, and the cost calculator does this from your ZIP. The 38 kWh gap to the class median of 3,531 kWh turns into a cost only at your rate, so no amount is given here. The modeled installed-cost range appears in its own block on this page with its source and date. It is a modeled range, not a quote. To look for a unit in the same class as PROE40 T2 RH95, you can find a same-class replacement by model number.
