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).

Label numbers this filing covers (4)

The model number on your rating plate may be any of these; each is filed under this one listing.

  • CPROPH50 T2 RH400-15

  • ECEPH50 T2 RH400-15
  • PROPH50 T2 RH400-15

If you are checking the Rheem PROPH50 T2 RH375-15, 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 class median of 3,493 kWh, 26th lowest of 452 electric tank models.


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
2020-04-30
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)
R-134a, GWP 1430

Installed cost and service life

Service 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.

What these figures mean

The figure of 866 kWh is a calculation by this site, not a registry entry and not a metering result. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 3.75 with the DOE test's daily hot-water draw for the medium pattern. The source is DOE CCD, retrieved 2026-10-25. The comparison group is the 452 models registered as an electric tank at the medium draw pattern. Their median is 3,493 kWh, so this model sits 2,627 kWh below it. That places it 26th lowest in the group, inside the lowest quarter for energy use. The calculation method is documented separately.

The figure applies to households whose hot-water use matches the medium draw pattern. For any other use, a figure is not available on this page and it is not estimated here. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 52 gallons for a rated volume of 45 gallons. A household whose peak first-hour demand is above 52 gallons is not covered by that rating. If your fuel, space or size differ, the water heater selector filters by those. To compare within the same class, you can find a same-class replacement by model number.

Read the rest

Running cost is not stated in the text because it depends on your own utility electricity tariff. The cost calculator takes your ZIP and applies the local rate to 866 kWh. Read that result as a cost at the federal test's draw, not as a bill forecast, because this page has no data on how much hot water your household actually uses. The modeled installed-cost range appears in its own block with its source and date, and it is not repeated here. The comparison against the 3,493 kWh median holds only for electric tank models at the medium draw pattern. A gas unit or another draw pattern would need a separate comparison.
