Flow where you live

The heater gives less flow when colder incoming water needs a bigger rise.

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.

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 0.8 gallons per minute. The electric tankless type has a median flow of 0.7 gallons per minute. Its flow at a 67°F rise trails 131 of the 337 electric tankless models.

In the test, 6% of its energy does not reach the hot water (UEF 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. 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).

Its test figures match those of one other basic model. The brand name on that one is A. O. Smith. For the full group, see the A. O. Smith UPVA-80Y 1**.
