Stiebel Eltron DHC 3-1 Trend

Stiebel Eltron DHC 3-1 Trend is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.98 and a certified flow of 0.3 gal/min at a 67°F rise.

  • Electric tankless water heater

Flow where you live

Colder incoming water needs a bigger rise, so the heater gives 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 0.3 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 0.3 gallons per minute of water from 58°F to 125°F in the test. The median electric tankless model heats 0.7 gallons per minute by 67°F. Among 337 electric tankless models, 271 give more flow at a 67°F rise.

In tests, 98% of the energy it uses ends up as hot water (UEF 0.98). The daily hot water use in the test, called its draw pattern, was very small. Its UEF is lower than that of 10 of the 272 electric tankless models with its draw pattern. A UEF of 0.96 is the median for its type and draw pattern. While it heats water, 99% of the energy used goes into the water (its recovery efficiency).
