RHEEM/RUUD PROE28 S2 RH95
0.92 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
If you are checking this unit against a quote or a label, RHEEM/RUUD PROE28 S2 RH95 uses 2,439 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against for a one- or two-person household. That is 0 kWh from its class median of 2,439 kWh.
Energy use per year
2,439 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.
That is equal to the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.
Solid line: this model (2,439 kWh). Dashed line: the class median.

What it costs to install
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.
The annual energy figure on this page does not depend on this range and is unaffected.
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.

The figure of 2,439 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw and only to electricity. A household that draws more or less hot water than the test will use more or less energy. It is a standardized test value, not a measurement from a home. The steps are set out on the page on how the annual cost is calculated.
This model is compared with the 163 models registered as an electric tank at the low draw pattern. The class median is 2,439 kWh, and this model differs from it by 0 kWh. The class data also list it at 19th lowest energy use of 163, which places it in the lowest quarter of its class. This page reports both statements as given and does not reconcile them further. The comparison holds only inside this class and draw pattern. It says nothing about other fuels, other tank types or other draw patterns.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 45 gallons for this model, and the rated volume is 25 gallons. The energy figure fits a household whose hot-water use resembles the low draw pattern. It does not describe a household that uses noticeably more hot water than that. The running cost is not stated here because it depends on your own electricity rate. The cost calculator computes it from your ZIP. An installed price range is not published, because this model's ratings lie outside the range the cost database was fitted on.
