Mits Air US3-RSJ-15/190RDVN3-L3
3.75 UEF DOE CCD · 2026-09-19Grade A: where this UEF sits among the 426 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).
If you are checking the Mits Air US3-RSJ-15/190RDVN3-L3, this electric tank uses 866 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,665 kWh below the 3,531 kWh median of the 426 electric tanks registered at the same draw pattern.
Energy use per year
866 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 21 of 426, lowest energy first.
Solid line: this model (866 kWh). Dashed line: the class median.

This site computed the 866 kWh figure. The registry does not list it. The calculation combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw the DOE test sets for the medium draw pattern. This model's UEF is 3.75. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. A household that draws more or less hot water each day will use a different amount of electricity. This model ranks 21st lowest for energy use among the 426 electric tanks registered at the medium draw pattern. The method behind the figure is set out in how the annual cost is calculated.
Two more registry values show which homes the rating covers. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 69 gallons for this model. Its rated volume is 47 gallons. DOE uses the medium draw pattern to represent a typical household's daily hot-water use. The 866 kWh figure therefore applies to homes whose use is close to that pattern. A home that needs more than 69 gallons in its busiest hour needs more than this rating covers. The registry data here does not say how the unit performs outside the test conditions, so that is not available. To compare other tanks by fuel, space and size, use the water heater selector. To match this unit within its class, look up a same-class replacement by model number.
The running cost is not stated here because it depends on your own utility's electricity tariff. The page computes it from your ZIP and does not estimate it. The energy gap applies at any tariff. At the medium draw pattern, this model uses 2,665 kWh less electricity a year than the class median of 3,531 kWh. Your rate per kWh applies to that difference in the same way it applies to the total. To see that gap priced at your own rate, enter your ZIP in the cost calculator for your own area. The installed price on this page appears in its own block with its source and date. It is a modeled range, not a quote.
