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 0.4 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-35E 1** | 0.92 | 0.4 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
At a 67°F rise, its flow in the test is 0.4 gallons per minute. The median flow among electric tankless models is 0.7 gallons per minute. Its flow at a 67°F rise trails 233 of the 337 electric tankless models.
In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). Its test ran at the very small level of daily hot water use. Of 272 electric tankless models with the same draw pattern, 249 have a higher UEF and 7 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. Those basic models are sold with A. O. Smith and American as their brand names. For the full group, see the A. O. Smith UPVA-35E 1** page.
