Stiebel Eltron DHC-E 10
0.94 UEF DOE CCD · 2026-09-19Grade F: where this UEF sits among the 271 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tankless unit, very small draw pattern (small units - a single bathroom, or a point-of-use heater under a sink).
If you are checking the Stiebel Eltron DHC-E 10, an electric tankless unit, it uses 628 kWh of electricity a year. That figure holds at the very small draw pattern, the standard daily hot-water usage DOE tests against. It sits 13 kWh above the median of 615 kWh for the 271 models in its class.
Energy use per year
628 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 above the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 188 of 271, lowest energy first.
Solid line: this model (628 kWh). Dashed line: the class median.

The 628 kWh figure is computed by this site, not taken from the registry. It combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the very small draw pattern. For this model the UEF is 0.94. The registry values come from the DOE CCD, retrieved 2026-09-19. Among electric tankless units registered at this draw pattern, the model ranks 188th lowest energy use of 271. That rank places it in the second-highest quarter of its class for energy use. The page on how the annual cost is calculated sets out the method behind the energy figure and its conditions.
The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The registry lists this model's maximum flow rate in gallons per minute as 1. The 628 kWh figure applies only at the test's daily draw for that pattern. This data has no energy value for this model under heavier daily use, so that figure is not available here. A reader matching a unit to a larger demand can compare options with the selector by fuel, space and size. A reader replacing this exact unit can find a same-class replacement by model number, which keeps the comparison within the same draw pattern and heater type.
The text on this page states no running cost for this model. The cost of 628 kWh of electricity a year depends on your own utility's electricity tariff. For that reason the page computes it from your ZIP in the cost calculator on your own ZIP, not from a national figure. That result carries the same condition as the energy figure: the very small draw pattern at the federal test's daily draw. Any running cost for a different daily draw is not available from this data. The installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote from an installer.
