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 1.1 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.

Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|

UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 1.2 gallons per minute of water from 58°F to 125°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Of 337 electric tankless models, 64 have a higher flow than this one.
In tests, 94% of the energy it uses ends up as hot water (UEF 0.94). The daily hot water use in the test, called its draw pattern, was very small. Its UEF is lower than that of 187 of the 272 electric tankless models with its draw pattern. For its type and draw pattern, the median UEF is 0.96. When it runs, 94% of the energy it uses reaches the water (its recovery efficiency).
It is the basic model for ET011KA1G and ET011KA3G. There are 3 more basic models with the same test figures. The Fogatti, Mizudo, and ORBEK brands list one or more of them. For the full group, see the Fogatti ET011.
