Hot Water List

Aquapower DHC-E 8

Aquapower DHC-E 8 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 8.

Certified figures

Flow at a 67°F rise
0.7gallons per minute
UEF
0.96Uniform energy factor

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 0.7 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 0.7 gallons per minute. The median flow among electric tankless models is 0.7 gallons per minute. Its flow at a 67°F rise trails 154 of the 337 electric tankless models.

In tests, 96% of the energy went to hot water, so its UEF is 0.96. The daily hot water use in the test, called its draw pattern, was very small. Its UEF is lower than that of 77 of the 272 electric tankless models with its draw pattern. 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).

There are 3 more basic models with the same test figures. Of those, one or more are under the Stiebel Eltron brand. For the full group, see the Stiebel Eltron DHC-E 8.
