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 5.0 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 5.2 gallons per minute of water by 67°F in the test. The median gas tankless model heats 4.8 gallons per minute by 67°F. Its flow at a 67°F rise trails 145 of the 487 gas tankless models.
All 5 of its model numbers are ENERGY STAR certified. In tests, 95% of the energy went to hot water, so its UEF is 0.95. The daily hot water use in the test, called its draw pattern, was high. Its UEF is lower than that of 49 of the 399 gas tankless models with its draw pattern. On its draw pattern, the median gas tankless UEF is 0.93. Of the energy it spends heating water, 99% ends up in it (its recovery efficiency).
All 5 of its model numbers carry the same certified figures. All of its test figures are shared by 8 other basic models. Of those, one or more are under the Elios and Kepler brands. For the full group, see the Elios EROD180N0000.
In 7 states, 6 rebate programs may accept it. Another 2 programs may accept it if it meets their other terms.
