Aquapower DHC 10-2

Aquapower DHC 10-2 is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.94 and a certified flow of 1.0 gal/min at a 67°F rise.

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 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.

It heats 1.0 gallons per minute of water by 67°F in the test. The electric tankless type has a median flow of 0.7 gallons per minute. Its flow at a 67°F rise trails 91 of the 337 electric tankless models.

In tests, 94% of the energy went to hot water, so its UEF is 0.94. Its test ran at the very small level of daily hot water use. Among 272 electric tankless models on its draw pattern, 187 have a higher UEF. On its draw pattern, the median electric tankless UEF is 0.96. Of the energy it spends heating water, 92% ends up in it (its recovery efficiency).
