Grade G: 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
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).

- RC40G-E
Checking the Ranein RC40G? It uses 3,493 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 3,493 kWh among 452 electric tank models, a difference of 0 kWh. This site computes the figure from registry data.
Energy use per year
3,493 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 second-lowest quarter of its class for energy use. That is equal to the median of 3,493 kWh for the 452 models registered in the same heater type and draw pattern; it ranks 174 of 452, lowest energy first.

From DOE CCD · 2026-10-25
- UEF (Uniform Energy Factor) how much hot water you get for each unit of energy the heater uses
- 0.93 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
- 57 gal
- Rated Storage Volume the tank size in gallons
- 40 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.

NLR REMDB (BLS PPI/ECI escalated) · 2026-04-01Service 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.

3,493 kWh/yr Grade G Cost on your ZIP
The figure of 3,493 kWh is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the daily hot-water draw the DOE test sets for this draw pattern. This model's UEF is 0.93. The fuel is electricity, and the source is DOE CCD, retrieved 2026-10-25. Because the figure is 3,493 kWh and the class median is 3,493 kWh, the difference is 0 kWh. The unit ranks 174th lowest energy use of 452, which puts it in the second-lowest quarter of its class for energy use. All of this holds only for the medium draw pattern.
The medium draw pattern is the one the figure was computed for. It suits a reader whose household hot-water use resembles that pattern, and for that reader 3,493 kWh is the number to compare with the class median of 3,493 kWh. It suits less well a reader whose use differs, because this data gives no figure for any other pattern. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons on a rated volume of 40 gallons. These are registry values and do not show how a given home will use them. To narrow options by fuel, space and size, use the water heater selector, or find a same-class replacement by model number.
Read the rest
Running cost is not stated in this text, because it depends on your own utility electricity tariff. The annual energy of 3,493 kWh is the quantity that tariff is applied to. The cost calculator on your own ZIP does that step, and the page on how the annual cost is calculated explains the method. The installed price range appears in its own block with its source and date, as a modeled range and not a quote, so it is not restated here. Not available from this data: metered use in a particular home, and any figure for a draw pattern other than medium. With a difference of 0 kWh from the class median, annual energy alone does not separate this model from the median unit of its class.
