866 kWh a year DOE CCD (opens in a new tab) (the U.S. Department of Energy’s Compliance Certification Database) · 2026-10-25UEF 3.75 filed efficiency; the yearly figure is computed from it
Grade A: where this UEF sits among the 452 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A heat pump water heater (filed by DOE as an electric tank, UEF 2.0 and up), medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).

If you are checking the Rheem PROPH50 T2 RH400-15, it uses 866 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,627 kWh below the 3,493 kWh median of 452 electric tank models registered at the same draw pattern.
Energy use per year
866 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 3,493 kWh for the 452 models registered in the same heater type and draw pattern; it ranks 26 of 452, lowest energy first.
Among the 153 heat pump water heaters at this draw pattern alone, it ranks 26 by lowest yearly energy.

What the registry files
From DOE CCD · 2026-10-25
- UEF (Uniform Energy Factor) how much hot water you get for each unit of energy the heater uses
- 3.75 Compared only with other models registered as an electric tank at the medium draw pattern.
- Draw Pattern the standard daily usage profile DOE tests the unit against
- Medium
- First Hour Rating how many gallons of hot water the unit can deliver in one hour, starting from a full tank
- 52 gal
- Rated Storage Volume the tank size in gallons
- 45 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.
From ENERGY STAR · 2026-10-25
- On the market since (ENERGY STAR) the date the manufacturer told ENERGY STAR the model went on sale
- 2024-06-24
- 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)

NLR REMDB (BLS PPI/ECI escalated) · 2026-04-01Service life: DOE’s cost database assumes 14.8 years for heat pump tanks. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

866 kWh/yr Grade A Cost on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.75 for this model. This site combined that value with the DOE test's daily hot-water draw for the medium draw pattern. The result is 866 kWh of electricity a year. The figure is computed by this site, not reported by the registry, and it uses DOE CCD data retrieved 2026-10-25. It describes test conditions, not any particular home. A household that draws more or less hot water than the medium pattern will use a different amount, and this data does not say by how much. The methodology page shows how the calculation is done.
Among the 452 electric tank models registered at the medium draw pattern, this unit ranks 26th lowest for energy use, which places it in the lowest quarter of its class. Its 866 kWh sits 2,627 kWh below the class median of 3,493 kWh. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 52 gallons, and the rated volume is 45 gallons. The comparison applies to households whose use matches the medium pattern. This data does not state whether 52 gallons covers any specific household's busiest hour. The water heater selector filters by fuel, space and size.
Read the rest
The running cost is not stated in the text, because it depends on your own utility electricity tariff. The cost calculator applies the rate for your ZIP to the 866 kWh figure, which holds only at the medium draw pattern. The installed price range appears in its own block, labelled as a modeled installed-cost range and not a quote, so it is not restated here. If you are checking a swap, you can find a same-class replacement by model number and compare it with PROPH50 T2 RH400-15. Ranking 26th lowest of 452 describes energy use at the test draw. Your bill also depends on your rate and your actual hot-water use, and neither is in this data.
