Novair US3-RSJ-15/300RDVN3-L3
4 UEF DOE CCD · 2026-09-19Grade B: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking this unit's figures, Novair US3-RSJ-15/300RDVN3-L3 uses 1,240 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 66 kWh below the class median of 1,306 kWh across 194 electric tank models registered at the same pattern.
Energy use per year
1,240 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 below the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 30 of 194, lowest energy first.
Solid line: this model (1,240 kWh). Dashed line: the class median.

UEF 4 · Grade B Price it on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 4 for Novair US3-RSJ-15/300RDVN3-L3. This site combined that UEF with the DOE test's daily hot-water draw for the draw pattern to get 1,240 kWh of electricity a year. The registry does not publish this figure; the site computed it from DOE CCD data retrieved on 2026-09-19. It holds only at the test's draw, so a home that uses more or less hot water will use a different amount. The model sits 66 kWh below the class median of 1,306 kWh. It ranks 30th lowest for energy use among 194 electric tank models, which places it in the lowest quarter of its class.
The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 91 gallons, with a rated volume of 74 gallons. The figure of 1,240 kWh applies to homes whose use is close to the test's draw. It does not describe a household with a lighter or heavier draw, and the data does not show whether these capacities meet a specific home's peak demand. To compare other fuels or sizes, use the water heater selector by fuel, space and size. To look at a same-class alternative, find a replacement by model number.
Running cost is not stated here because it depends on your own utility electricity tariff. The calculation is the annual energy of 1,240 kWh at the high draw pattern, multiplied by your rate per kilowatt-hour. The cost calculator on your own ZIP applies your rate to that figure, and the method behind the annual cost is described separately. The 66 kWh gap to the class median of 1,306 kWh converts to a yearly difference by the same rate. The installed price range appears in its own block on this page with its source and date. It is a modeled range, not a quote, and it is not repeated here. The energy figure was retrieved on 2026-09-19 and reflects the federal test, not measured use in a home.
