Aquapower DHC-E 12
Aquapower DHC-E 12 is in the DOE listing as of Oct 19, 2026.
- Electric tankless water heater
- 2 listed models
ENERGY STAR certification does not cover this type of water heater.
Its figures are also listed under Stiebel Eltron DHC-E 12.

Change your hour and flowFlow 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 1.1 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 |
|---|---|---|---|---|
| AQE 12 | 0.93 | 1.2 | 95% | Very small |
| DH 120 | 0.93 | 1.2 | 95% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It heats 1.2 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. Among 337 electric tankless models, 64 give more flow at a 67°F rise.
In the test, 7% of its energy does not reach the hot water (UEF 0.93). Its test ran at the very small level of daily hot water use. Its UEF is lower than that of 217 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, 95% of the energy used goes into the water (its recovery efficiency).
Its 2 model numbers are AQE 12 and DH 120. There is one more basic model with the same test figures. That one carries the Stiebel Eltron brand name. You can find the whole group on the page for the Stiebel Eltron DHC-E 12.
