Hot Water List

EEMAX SPEX8208

EEMAX SPEX8208 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 AM008277T.

Certified figures

Flow at a 67°F rise
0.8gallons per minute
UEF
0.96Uniform energy factor

Flow where you live

Colder incoming water needs a bigger rise, so the heater gives 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 0.8 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.

At a 67°F rise, its flow in the test is 0.8 gallons per minute. The median flow among electric tankless models is 0.7 gallons per minute. Its flow at a 67°F rise trails 131 of the 337 electric tankless models.

In tests, 96% of the energy went to hot water, so its UEF is 0.96. In the test, daily hot water use was set to very small (its draw pattern). Of 272 electric tankless models with the same draw pattern, 77 have a higher UEF. Its UEF is the median for its type and draw pattern. Of the energy it spends heating water, 95% ends up in it (its recovery efficiency).

There are 7 more basic models with the same test figures. Of those, one or more are under the KWICKSHOT and Rheem brands. For the full group, see the Rheem AM008277T.
