BOCK RE250LN*-*****
0.92 UEF DOE CCD · 2026-09-19Grade G: 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 verifying BOCK RE250LN*-*****, it uses 3,531 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 3,531 kWh across 426 electric tank models, a difference of 0 kWh. It ranks 213th lowest in energy use.
Energy use per year
3,531 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 equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

The annual figure of 3,531 kWh is computed by this site, not published by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. The site combines that with the daily hot-water draw the DOE test assigns to the medium draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw. It is a calculation from the registry's UEF, not a measurement of an installed unit. Households with different hot-water use will have different energy use.
Among the 426 models registered as an electric tank at the medium draw pattern, this unit ranks 213th lowest in energy use. The class median is 3,531 kWh, and this model differs from it by 0 kWh. That places it in the second-lowest quarter of its class for energy use. The position describes energy use only. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 61 gallons. The rated volume is 43 gallons. The unit suits a household whose busiest hour stays within that first hour rating. It suits less well a household whose busiest hour draws more than 61 gallons.
Running cost is not stated in this text, because it depends on your own utility electricity tariff. The cost calculator for your own ZIP applies your rate to the 3,531 kWh figure. The page on how the annual cost is calculated explains the method. This site does not estimate a cost for you. The modeled installed-cost range appears in its own block with its source and date, and it is not a quote.
