Hot Water List

Stiebel Eltron DHC-E 6-2 Trend

Stiebel Eltron DHC-E 6-2 Trend is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.98 and a certified flow of 0.6 gal/min at a 67°F rise.

Its certified flow is 0.6 gal/min at a 67°F rise, while The Home Depot advertises 0.91 gal/min, no rise stated (Archived copy, Nov 10, 2025), so a comparison at the same rise is not possible.

  • Electric tankless water heater
  • 3 listed models

ENERGY STAR certification does not cover this type of water heater.

Flow where you live

A bigger rise from colder incoming water leaves the heater with less flow.

Cold water
Cold water must be at least 10°F colder than the hot water setting.
Flow estimate
The estimate uses the lowest certified flow among the listed models. It is about 0.6 gal/min at a 70°F rise.

Flow limits

  • The estimate excludes the flow needed to turn the heater on, heat lost in pipes, and installation.
  • Cold water from a well or long pipe run can differ from the temperature you enter.
  • Without a stated flow limit, estimates for warmer water may exceed the heater’s actual flow.

UEF is the uniform energy factor. A dash means the model has no such figure.

It warms 0.6 gallons per minute of water from 58°F to 125°F in the test. The electric tankless type has a median flow of 0.7 gallons per minute. Of 337 electric tankless models, 179 have a higher flow than this one.

In tests, 98% of the energy went to hot water, so its UEF is 0.98. In the test, daily hot water use was set to very small (its draw pattern). Among 272 electric tankless models on its draw pattern, 10 have a higher UEF. A UEF of 0.96 is the median for its type and draw pattern. Of the energy it spends heating water, 98% ends up in it (its recovery efficiency).

Its 3 model numbers are DHC-E 6-2 Plus, DHC-E 6-2 Trend, and DHX 6-2 Trend. There are 3 more basic models with the same test figures. Of those, one or more are under the Aquapower brand.
