0.92 UEF DOE CCD · 2026-09-19Grade C: where this UEF sits among the 21 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank your utility can shift to off-peak hours, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking the Ruud MRG85245, it uses 5,392 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 5,392 kWh, a difference of 0 kWh. It ranks 3rd lowest in energy use of 21 models in its class.
Energy use per year
5,392 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 5,392 kWh for the 21 models registered in the same heater type and draw pattern; it ranks 3 of 21, lowest energy first.
Solid line: this model (5,392 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.

This site computes the 5,392 kWh figure; the registry does not publish it. The figure combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. For this model the UEF is 0.92. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only at the test's daily draw. A household that draws more or less hot water will use a different amount. The unit is an electric tank your utility can shift to off-peak hours. The figure shows how much electricity it uses, but not when it uses it. The method is set out in how the annual cost is calculated.
The high draw pattern describes a larger household, or one where showers and laundry overlap. This model's rated volume is 84 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 77 gallons. The comparison covers the 21 models registered as an electric tank your utility can shift to off-peak hours at the high draw pattern. Within that group, the rank of 3rd given above places this model in the lowest quarter for energy use. The comparison does not include models of other heater types or at other draw patterns. To check another model in the same class, use find a same-class replacement by model number.
For a smaller household, the 5,392 kWh figure does not describe likely use, because it depends on the daily draw of the high draw pattern. The running cost is not stated here. It depends on your own utility's electricity tariff, so the page works it out from your ZIP. The cost calculator on your own ZIP gives that result. An installed price range is not published for the Ruud MRG85245. This model's ratings lie outside the range the cost database's model was fitted on. The range is not extended beyond that. This page therefore cannot show what installing this unit would cost.
