Aquapower DHC 3-2 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 Rheem SPEX3208T.

Change your hour and flowFlow 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.
Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| AQM 3-2 | 0.97 | 0.3 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 0.3 gallons per minute of water from 58°F to 125°F in the test. The median electric tankless model heats 0.7 gallons per minute by 67°F. Its flow at a 67°F rise trails 271 of the 337 electric tankless models.
In tests, 97% of the energy went to hot water, so its UEF is 0.97. In the test, daily hot water use was set to very small (its draw pattern). Among 272 electric tankless models on its draw pattern, 37 have a higher UEF. A UEF of 0.96 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 of its test figures are shared by 11 other basic models. Those basic models are sold with EEMAX, Rheem, and Stiebel Eltron as their brand names. For the full group, see the Rheem SPEX3208T.
