Flow where you live

A bigger rise from colder incoming water leaves the heater with 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 5.5 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.

It heats 5.7 gallons per minute of water by 67°F in the test. The gas tankless type has a median flow of 4.8 gallons per minute. Its flow at a 67°F rise trails 60 of the 487 gas tankless models.

It is ENERGY STAR certified under its single model number. In the test, 5% of its energy does not reach the hot water (UEF 0.95). Its test ran at the high level of daily hot water use. Of 399 gas tankless models with the same draw pattern, 49 have a higher UEF. For its type and draw pattern, the median UEF is 0.93. When it runs, 99% of the energy it uses reaches the water (its recovery efficiency).

Its test figures match those of 15 other basic models. Between them, those basic models carry 4 other brand names. For the full group, see the Elios EROD199N0000.

In 7 states, 6 rebate programs may accept it. Another 2 rebate programs may accept it if it meets their other terms.
