Certified figures

Flow at a 67°F rise
3.9gallons per minute
UEF
0.82Uniform energy factor

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 3.7 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 3.9 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. Among 487 gas tankless models, 399 give more flow at a 67°F rise.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 82% of the energy it uses ends up as hot water (UEF 0.82). In the test, daily hot water use was set to medium (its draw pattern). Of 77 gas tankless models with the same draw pattern, 30 have a higher UEF. On its draw pattern, its UEF is also the median gas tankless UEF. While it heats water, 84% of the energy used goes into the water (its recovery efficiency).

All of its test figures are shared by 2 other basic models. Those basic models are sold with Ranein as their brand names.
