Checking the Rheem PROPH40 T2 RH400-30? At the medium draw pattern, the standard daily hot-water usage DOE tests against, it uses 848 kWh of electricity a year. That is 2,645 kWh below the class median of 3,493 kWh for 452 electric tank models. It ranks 14th lowest, in the lowest quarter of its class.
Energy use per year
848 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 14 of 452, lowest energy first.
Among the 153 heat pump water heaters at this draw pattern alone, it ranks 14 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
- 3.83 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
- 60 gal
- Rated Storage Volume the tank size in gallons
- 36 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)
- R-134a, GWP 1430
Installed cost and service life
Not published: Installed cost range
This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
Ask installers for a written quote that names this model number; heat pump installs are quoted unit by unit. State programs that pay toward one are listed on the rebates page.
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.

Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

848 kWh/yr Grade A Cost on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.83 for this Rheem PROPH40 T2 RH400-30, an electric tank. The annual figure of 848 kWh is not a registry entry. This site computed it from that UEF and the daily hot-water draw in the DOE test for the medium draw pattern. The source is DOE CCD, retrieved 2026-10-25. The figure is therefore valid only at the test's draw, and it says nothing about a particular household's measured use. Against the class median of 3,493 kWh, the model sits 2,645 kWh lower, which places it 14th lowest of 452.
The registry gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 60 gallons and a rated volume of 36 gallons. The energy figure applies to the medium draw pattern only. A household that draws more or less hot water than the test draw will use a different amount of electricity, and the registry data do not show by how much. For the same reason, the rank of 14th lowest of 452 compares only electric tank models registered at this draw pattern. To compare size, space and fuel, use the water heater selector. To find a same-class unit by model number, use the replacement finder.
Read the rest
The running cost is not stated here because it depends on your own utility electricity rate. The calculation multiplies 848 kWh by that rate, and the cost calculator does this from your ZIP code. The method is described on the methodology page. An installed price range is not published for this model: its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. The class median of 3,493 kWh is shown only as a reference point, and the difference of 2,645 kWh cannot be turned into a cost without a rate.
