Stiebel Eltron DHC-E 6-2 Trend
0.98 UEF DOE CCD · 2026-09-19Grade D: 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 6-2 Trend, an electric tankless unit, it uses 603 kWh of electricity a year. That figure holds at the federal test's daily hot-water draw for the very small draw pattern, the standard daily hot-water usage DOE tests against. It sits 12 kWh below its class median of 615 kWh.
Energy use per year
603 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 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 10 of 271, lowest energy first.
Solid line: this model (603 kWh). Dashed line: the class median.

The 603 kWh figure is computed by this site. It is not taken from 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 very small draw pattern. For this model the UEF is 0.98, from DOE CCD data retrieved 2026-09-19. The page on how the annual figure is calculated sets out each step. It is compared with the 271 models registered as an electric tankless unit at the very small draw pattern. Against that class, this model ranks 10th lowest in energy use. That places it in the lowest quarter of its class, 12 kWh below the 615 kWh median.
The very small draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. The 603 kWh figure applies to that level of use only. The registry lists this model's maximum flow rate in gallons per minute as 0.6. Demand above 0.6 gallons per minute is outside what the registry lists for this unit. A home that needs whole-house hot water falls under a different draw pattern. This page gives no energy figure for that use, so it is not available here. To compare units by fuel, space and size, use the water heater selector. To match this unit within its class, search same-class replacements by model number.
This page does not state a running cost for the Stiebel Eltron DHC-E 6-2 Trend. That cost depends on your own utility's electricity rate, which is not part of the registry data. The page applies the rate for your ZIP to the 603 kWh annual figure. The cost calculator for your own ZIP does the same calculation. The class median is 615 kWh, so any rate applies to a yearly gap of 12 kWh between this model and that median. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
