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 0.6 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 6-2 | 0.94 | 0.6 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 0.6 gallons per minute of water from 58°F to 125°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Among 337 electric tankless models, 179 give more flow at a 67°F rise.
In tests, 94% of the energy went to hot water, so its UEF is 0.94. Its test simulated a day of very small hot water use (its draw pattern). Of 272 electric tankless models with the same draw pattern, 187 have a higher UEF and 55 a lower one. 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 one other basic model. The brand name on that one is Stiebel Eltron. You can find the whole group on the page for the Stiebel Eltron Mini 6-2.
