RINNAI US3-RSJ-15/190RDVN3-L4
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 RINNAI US3-RSJ-15/190RDVN3-L4 against the registry, this site calculates its annual energy use at 866 kWh of electricity. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,665 kWh below the class median of 3,531 kWh for electric tanks at that 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.

UEF 3.75 · Grade A Price it on your ZIP
The registry does not list the 866 kWh figure. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the medium pattern. The registry lists a UEF of 3.75 for this model. The source is the DOE CCD, retrieved on 2026-09-19. There are 426 models registered as an electric tank at the medium draw pattern. This one ranks 21st lowest in energy use among them, against a class median of 3,531 kWh a year. Both figures assume the test's daily draw. If your household draws more or less hot water than the test assumes, your own use will differ from 866 kWh. The steps behind the annual energy and cost figures are published separately.
The medium draw pattern represents a typical mid-sized household with a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 71 gallons. Its rated volume is 46 gallons. Those two figures describe how much hot water the unit can supply, while 866 kWh describes its energy use at the test draw. A household whose busiest hour needs more than 71 gallons needs more than this rating covers. A household that uses less hot water than the medium pattern should use less than 866 kWh. This page does not give an amount for that case. To compare other units, use the water heater selector by fuel, space and size.
This page does not give a running cost for this model. The cost of 866 kWh of electricity depends on your own utility tariff, and this page does not know your rate. The running-cost calculator for your own ZIP applies your local rate to this model's annual figure. The 2,665 kWh gap to the class median is a gap in energy use. Its value on a bill also depends on your rate, so this page does not state it. This page shows an installed-cost range in its own block, with its source and date. That range is modeled and is not a quote from an installer.
