Stiebel Eltron DHC-E 10-2 Trend
Stiebel Eltron DHC-E 10-2 Trend is in the DOE listing as of Oct 26, 2026.
It has a certified UEF of 0.96 and a certified flow of 1.0 gal/min at a 67°F rise.
Its certified flow is 1.0 gal/min at a 67°F rise, while The Home Depot advertises 1.87 gal/min, no rise stated (Archived copy, May 21, 2025), so a comparison at the same rise is not possible.
- Electric tankless water heater
- 4 listed models
ENERGY STAR certification does not cover this type of water heater.

The heater gives less flow when colder incoming water needs a bigger rise.
- 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 1.0 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.
At a 67°F rise, its flow in the test is 1.0 gallons per minute. The median flow among electric tankless models is 0.7 gallons per minute. Among 337 electric tankless models, 91 give more flow at a 67°F rise.
In tests, 96% of the energy went to hot water, so its UEF is 0.96. Its test simulated a day of very small hot water use (its draw pattern). Among 272 electric tankless models on its draw pattern, 77 have a higher UEF. Its UEF is the median for its type and draw pattern. While it heats water, 98% of the energy used goes into the water (its recovery efficiency).
All 4 of its model numbers carry the same certified figures.
- Every Stiebel Eltron basic model
- Every electric tankless water heater certified at 1.0 to 1.9 gallons per minute
