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 warms 5.2 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, 145 have a higher flow than this one.
It is ENERGY STAR certified under its single model number. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). In the test, daily hot water use was set to high (its draw pattern). Of 399 gas tankless models with the same draw pattern, 49 have a higher UEF and 217 a lower one. A UEF of 0.93 is the median for its type and draw pattern. Of the energy it spends heating water, 99% ends up in it (its recovery efficiency).
There are 8 more basic models with the same test figures. The Kepler and Midea brands list one or more of them.
It may qualify for 6 rebate programs in 7 states. Another 2 programs may accept it if it meets their other terms.
