Grade G: where this UEF sits among the 170 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).

- RC25G-E
Checking the Ranein RC25G, an electric tank? It uses 2,439 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That pattern stands for a one- or two-person household. The figure equals the median of the 170 electric tanks registered at this pattern: 2,439 kWh, a difference of 0 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.
This model is in the lowest quarter of its class for energy use. That is equal to the median of 2,439 kWh for the 170 models registered in the same heater type and draw pattern; it ranks 24 of 170, lowest energy first.

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
- 0.92 Compared only with other models registered as an electric tank at the low draw pattern.
- Draw Pattern the standard daily usage profile DOE tests the unit against
- Low
- First Hour Rating how many gallons of hot water the unit can deliver in one hour, starting from a full tank
- 42 gal
- Rated Storage Volume the tank size in gallons
- 25 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.
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. The yearly running cost on this page does not depend on it.
Service life: DOE’s cost database assumes 14.8 years for electric resistance tanks. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

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.

2,439 kWh/yr Grade G Cost on your ZIP
This site computes the 2,439 kWh figure; the registry does not publish it. It 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 low pattern. For the RC25G, that UEF is 0.92. The source is the DOE CCD, retrieved 2026-10-25. The result holds only at the federal test's daily draw. The data gives no energy figure for any other daily usage. A household that draws more or less hot water than the test assumes cannot read its own use from this number. The steps behind the figure are set out on the page explaining how the annual cost is calculated.
Read the rest
Within its class, the RC25G ranks 24th lowest in energy use of 170 electric tanks at the low draw pattern. That rank places it in the lowest quarter of the class, while its figure equals the class median. The data does not say how many models share the same annual figure. The gap between rank and median therefore cannot be explained from this data. The tank holds 25 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 42 gallons. For a household using more hot water daily than the low pattern, this page has no figure. The selector by fuel, space and size filters on those needs. For a like-for-like check, you can find a same-class replacement by model number.
This text does not state the running cost. It depends on your own utility's electricity tariff. The page applies your rate to the 2,439 kWh figure once you enter a ZIP in the cost calculator on your own ZIP. Any cost shown there carries the same condition as the energy figure: the low draw pattern at the federal test's daily draw. An installed price range is not published for the RC25G. Its ratings lie outside the range the cost database's model was fitted on. The site does not stretch that range past it. The installed price for this model is therefore not available here.
