Aquapower Mini-E 6-2

Aquapower Mini-E 6-2 is in the DOE listing as of Oct 19, 2026.

  • Electric tankless water heater
  • 1 listed model

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

Its figures are also listed under Stiebel Eltron DHC-E 6-2 Trend.

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 0.6 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.

At a 67°F rise, its flow in the test is 0.6 gallons per minute. The median electric tankless model heats 0.7 gallons per minute by 67°F. Its flow at a 67°F rise trails 179 of the 337 electric tankless models.

In the test, 2% of its energy does not reach the hot water (UEF 0.98). Its test simulated a day of very small hot water use (its draw pattern). Its UEF is lower than that of 10 of the 272 electric tankless models with its draw pattern. For its type and draw pattern, the median UEF is 0.96. While it heats water, 98% of the energy used goes into the water (its recovery efficiency).

All of its test figures are shared by 3 other basic models. The Stiebel Eltron brand lists one or more of them. You can find the whole group on the page for the Stiebel Eltron DHC-E 6-2 Trend.
