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 0.5 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 5-2 | 0.97 | 0.5 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 0.5 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 204 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). Of 272 electric tankless models with the same draw pattern, 37 have a higher UEF and 195 a lower one. For its type and draw pattern, the median UEF is 0.96. Of the energy it spends heating water, 98% ends up in it (its recovery efficiency).
There are 4 more basic models with the same test figures. They are listed under 4 other brands, one each. You can find the whole group on the page for the Rheem SPEX55T.
