If you are checking this unit against the registry, the Rheem PROPH65 T2 RH375-SO uses 1,225 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 81 kWh below the class median of 1,306 kWh for 204 electric tank models.
Energy use per year
1,225 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.
This model is in the lowest quarter of its class for energy use. That is below the median of 1,306 kWh for the 204 models registered in the same heater type and draw pattern; it ranks 22 of 204, lowest energy first.
Among the 181 heat pump water heaters at this draw pattern alone, it ranks 22 by lowest yearly energy.

From DOE CCD · 2026-10-25
- UEF (Uniform Energy Factor) how much hot water you get for each unit of energy the heater uses
- 4.05 Compared only with other models registered as an electric tank at the high draw pattern.
- Draw Pattern the standard daily usage profile DOE tests the unit against
- High
- First Hour Rating how many gallons of hot water the unit can deliver in one hour, starting from a full tank
- 75 gal
- Rated Storage Volume the tank size in gallons
- 59 gal Rated volume is the size the registry files. The number in a model name is the maker's nominal size and can differ: a "40-gallon" model may be rated at 36.

- On the market since (ENERGY STAR) the date the manufacturer told ENERGY STAR the model went on sale
- 2022-12-05
- Connected / demand response (ENERGY STAR) whether the unit can take signals from your utility to shift when it heats, and by which standard (such as CTA-2045)
- Yes (CTA-2045-B)
- Refrigerant and GWP (ENERGY STAR) the refrigerant a heat pump unit uses and its global warming potential, a leak's climate effect relative to carbon dioxide (CO2 = 1)

1,225 kWh/yr Grade B Cost on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 4.05 for the Rheem PROPH65 T2 RH375-SO. This site combines that value with the DOE test's daily hot-water draw for the high draw pattern and arrives at 1,225 kWh of electricity a year. The figure is a calculation, not a metered result, and it rests on DOE CCD data retrieved 2026-10-25. Among the 204 models registered as an electric tank at the high draw pattern, this unit has the 22nd lowest energy use. That places it in the lowest quarter of its class, where the median is 1,306 kWh.
The gap from the class median is 81 kWh a year, and it holds only at the federal test's draw. This unit has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 75 gallons and a rated volume of 59 gallons. It is listed under the high draw pattern, which means a larger household, or one where showers and laundry overlap. A household whose daily use differs from the test draw may not see the 1,225 kWh figure, and this page cannot say by how much, because measured household use is not available. The water heater selector by fuel, space and size helps when the draw pattern does not fit.
Read the rest
Running cost is not stated here because it depends on your own utility electricity tariff. Multiplying 1,225 kWh by your rate gives the yearly electricity cost at the test draw. The cost calculator on your own ZIP does this for you, and the methodology for the annual cost explains each step. The modeled installed-cost range appears in its own block with its source and date, and it is a range, not a quote.
