Hot Water List

EEMAX AM012240T

EEMAX AM012240T is in the DOE listing as of Oct 19, 2026.

  • Electric tankless water heater
  • 1 listed model

ENERGY STAR certification does not cover this type of water heater.

Its figures are also listed under Rheem AM012240T.

Certified figures

Flow at a 67°F rise
1.1gallons per minute
UEF
0.95Uniform 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 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.

UEF is the uniform energy factor. A dash means the model has no such figure.

It heats 1.1 gallons per minute of water by 67°F in the test. The electric tankless type has a median flow of 0.7 gallons per minute. Among 337 electric tankless models, 82 give more flow at a 67°F rise.

In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). The daily hot water use in the test, called its draw pattern, was very small. Of 272 electric tankless models with the same draw pattern, 151 have a higher UEF. A UEF of 0.96 is the median for its type and draw pattern. When it runs, 93% of the energy it uses reaches the water (its recovery efficiency).

There is one more basic model with the same test figures. That one is listed under the Rheem brand. You can find the whole group on the page for the Rheem AM012240T.
