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 0.2 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-24K 1** | 0.93 | 0.2 | 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 0.2 gallons per minute. The median electric tankless model heats 0.7 gallons per minute by 67°F. Among 337 electric tankless models, 320 give more flow at a 67°F rise.
In tests, 93% of the energy went to hot water, so its UEF is 0.93. Its test simulated a day of very small hot water use (its draw pattern). Its UEF is lower than that of 217 of the 272 electric tankless models with its draw pattern. A UEF of 0.96 is the median for its type and draw pattern. Of the energy it spends heating water, 98% ends up in it (its recovery efficiency).
Its test figures match those of one other basic model. That one is listed under the A. O. Smith brand. For the full group, see the A. O. Smith UPVA-24K 1**.
