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 0.8 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 |
|---|---|---|---|---|
| UPVS-90E 1** | 0.93 | 0.8 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 0.8 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. Of 337 electric tankless models, 131 have a higher flow than this one.
In tests, 93% of the energy went to hot water, so its UEF is 0.93. The daily hot water use in the test, called its draw pattern, was very small. Of 272 electric tankless models with the same draw pattern, 217 have a higher UEF and 23 a lower one. For its type and draw pattern, the median UEF is 0.96. When it runs, 98% of the energy it uses reaches the water (its recovery efficiency).
All of its test figures are shared by 3 other basic models. The A. O. Smith, American, and RELIANCE WATER HEATERS brands list one or more of them. You can find the whole group on the page for the A. O. Smith UPVA-90E 1**.
