Stiebel Eltron DHC-E 10-2 Trend

0.96 UEF DOE CCD · 2026-09-19
E

Grade E: 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 10-2 Trend, it uses 615 kWh of electricity a year at the federal test. That figure is for the very small draw pattern, the standard daily hot-water usage DOE tests against. It equals its class median and ranks 77th lowest in energy use of 271 electric tankless units at this pattern.


Energy use per year

615 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 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 77 of 271, lowest energy first.

This model: 615 kWh

Solid line: this model (615 kWh). Dashed line: the class median.

Safety record

No CPSC recall names this model.

Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

What these figures mean

The 615 kWh figure is computed by this site, not taken from the registry. This unit's UEF, the ratio of hot water delivered to energy used, is 0.96 in the DOE CCD. We apply that ratio to the DOE test's daily hot-water draw for the very small draw pattern. The registry data was retrieved on 2026-09-19. Very small covers a single bathroom, or a point-of-use heater under a sink. The figure holds only at that test draw. Daily use above or below the test draw would change the annual figure. The steps are set out in how the annual cost is calculated.

The registry lists a maximum flow rate in gallons per minute of 1 for this model. A home needing hot water beyond a single bathroom or sink falls outside the pattern this unit was tested at. Within its class, the model sits in the second-lowest quarter for energy use. Its gap from the 615 kWh class median is 0 kWh. That means it uses the same electricity as the class median at the test draw. If you need an alternative in the same class, you can find a same-class replacement by model number. For other fuels or larger draw patterns, use the selector by fuel, space and size.

The running cost is not stated in this text. It depends on your own utility's electricity tariff, which varies by location. The page computes it from your ZIP, starting from the 615 kWh test-draw figure. You can check it with the cost calculator on your own ZIP. Your household's actual yearly use is not available here, because it depends on your own daily hot-water draw. The installed price range appears in its own block, as a modeled range and not a quote. Its source and date are shown there, not repeated here. At the same tariff, a model at the 615 kWh median would show the same computed cost.
