Hot Water List

Aquapower DHC 3-1

Aquapower DHC 3-1 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 A. O. Smith UPVA-30K 1**.

Certified figures

Flow at a 67°F rise
0.3gallons per minute
UEF
0.93Uniform energy factor

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 heats 0.3 gallons per minute of water by 67°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Of 337 electric tankless models, 271 have a higher flow than this one.

In the test, 7% of its energy does not reach the hot water (UEF 0.93). Its test simulated a day of very small hot water use (its draw pattern). Its UEF is lower than that of 217 of the 272 electric tankless models with its draw pattern. A UEF of 0.96 is the median for its type and draw pattern. Of the energy it spends heating water, 98% ends up in it (its recovery efficiency).

There are 6 more basic models with the same test figures. In all, 4 other brands list one or more of them. For the full group, see the A. O. Smith UPVA-30K 1** page.
