3.75 UEF DOE CCD · 2026-09-19
A

Grade 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).

Checking a listing for Bosch US3-RSJ-15/190RDVN3-L3? At the medium draw pattern, the standard daily hot-water usage DOE tests against, this electric tank uses 866 kWh a year. That is 2,665 kWh below the class median of 3,531 kWh, and it ranks 21st lowest energy use of 426 models.


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.

What these figures mean

This model's registry UEF, the ratio of hot water delivered to energy used, is 3.75. This site derives the annual figure from that value and the federal test's daily hot-water draw for the medium draw pattern, which gives 866 kWh of electricity a year. The registry does not publish that annual figure itself. The source is DOE CCD, retrieved on 2026-09-19. Across the 426 electric tank models registered at the medium draw pattern, the median is 3,531 kWh, so this unit sits 2,665 kWh below it. Its rank of 21st lowest puts it in the lowest quarter of its class. The calculation method is documented separately.

The figure suits a check where the household's hot-water use matches the medium draw pattern, because the test draw defines that condition. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 69 gallons, and the rated volume is 47 gallons. Those two values describe capacity, not energy use. A household whose morning demand exceeds the first hour rating is outside what this page can confirm. Annual energy for other draw patterns is not available here. To compare by fuel, space or size, use the water heater selector, or look up a same-class replacement by model number.

Running cost is not stated in this text, because it depends on the electricity tariff the reader pays. The page computes it from the reader's ZIP, and the cost calculator does the same for any ZIP. As a manual check, multiply 866 kWh by your rate per kilowatt-hour to get this model's yearly electricity cost at the medium draw pattern. Multiplying 2,665 kWh by the same rate gives the yearly difference from the class median of 3,531 kWh. The modeled installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote, and it is not repeated here.
