Flow 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 5.1 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.

It warms 5.3 gallons per minute of water from 58°F to 125°F in the test. The gas tankless type has a median flow of 4.8 gallons per minute. Of 487 gas tankless models, 120 have a higher flow than this one.

On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 82% of the energy it uses ends up as hot water (UEF 0.82). Its test simulated a day of high hot water use (its draw pattern). Of 399 gas tankless models with the same draw pattern, 243 have a higher UEF. For its type and draw pattern, the median UEF is 0.93. When it runs, 84% of the energy it uses reaches the water (its recovery efficiency).

Its test figures match those of one other basic model. That one carries the Vancepic brand name.
