BOCK RE240LN*-*****
0.92 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
If you are checking BOCK RE240LN*-*****, its annual energy use is 2,439 kWh of electricity at the low draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 2,439 kWh, a difference of 0 kWh, among 163 registered electric tank models.
Energy use per year
2,439 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 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.
Solid line: this model (2,439 kWh). Dashed line: the class median.

The figure of 2,439 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the low draw pattern. The registry lists a UEF of 0.92 for this model at the low draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure describes test conditions only, so a household that draws more or less hot water than the test will use a different amount. This page holds no measured data from any real installation, so that difference is unknown. The method for calculating annual cost sets out the steps.
Among the 163 electric tank models registered at the low draw pattern, this model has the 19th lowest energy use, which places it in the lowest quarter of its class. Its 2,439 kWh equals the class median of 2,439 kWh, a difference of 0 kWh. The unit suits a household whose hot-water use is close to the test's low draw pattern. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 45 gallons, and its rated volume is 34 gallons. A household that uses more hot water than the low draw pattern should compare these figures with its own peak hour demand. The water heater selector filters models by fuel, space and size.
The running cost is not stated in the text because it depends on your own utility electricity rate. The annual cost equals 2,439 kWh multiplied by your rate per kWh, at the low draw pattern. The cost calculator for your own ZIP does this for you. The installed price range appears in its own block with its source and date, as a modeled installed-cost range and not a quote, so it is not restated here. The energy figure reflects DOE CCD data retrieved 2026-09-19, and later registry changes are not included. To look up a same-class unit for RE240LN*-*****, use the replacement finder by model number.
