Hot Water List

KWICKSHOT TEF080V277

KWICKSHOT TEF080V277 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 SPEX80.

Certified figures

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

It heats 0.8 gallons per minute of water by 67°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Of 337 electric tankless models, 131 have a higher flow than this one.

In tests, 96% of the energy it uses ends up as hot water (UEF 0.96). Its test simulated a day of very small hot water use (its draw pattern). Among 272 electric tankless models on its draw pattern, 77 have a higher UEF. For its type and draw pattern, its UEF sits at the median. When it runs, 94% of the energy it uses reaches the water (its recovery efficiency).

There are 2 more basic models with the same test figures. Those basic models are sold with EEMAX and Rheem as their brand names. For the full group, see the Rheem SPEX80 page.
