Hot Water List

VEVOR TSD-180

VEVOR TSD-180 is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.96 and a certified flow of 1.9 gal/min at a 67°F rise.

  • Electric tankless water heater

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 1.8 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 1.9 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, 32 give more flow at a 67°F rise.

In tests, 96% of the energy it uses ends up as hot water (UEF 0.96). Of the energy it spends heating water, 99% ends up in it (its recovery efficiency).
