Hot Water List

KWICKSHOT TEF041V208

KWICKSHOT TEF041V208 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 SPEX4208.

Certified figures

Flow at a 67°F rise
0.4gallons per minute
UEF
0.97Uniform energy factor

Flow where you live

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 0.4 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 warms 0.4 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. Among 337 electric tankless models, 233 give more flow at a 67°F rise.

In tests, 97% of the energy went to hot water, so its UEF is 0.97. Its test ran at the very small level of daily hot water use. Its UEF is lower than that of 37 of the 272 electric tankless models with its draw pattern. For its type and draw pattern, the median UEF is 0.96. While it heats water, 97% of the energy used goes into the water (its recovery efficiency).

There are 2 more basic models with the same test figures. The EEMAX and Rheem brands list one or more of them. For the full group, see the Rheem SPEX4208 page.
