Hot Water List

GE GE27DNHPDG01

GE GE27DNHPDG01 is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.91 and a certified flow of 2.7 gal/min at a 67°F rise.

Its certified flow is 2.7 gal/min at a 67°F rise, while GE advertises 5.4 gal/min at the temperatures it states (Read Oct 5, 2026), so a comparison at the same rise is not possible.

  • Electric tankless water heater
  • 1 listed model

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

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 2.6 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.

GE27DNHPDG010.912.798%—

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

It warms 2.7 gallons per minute of water from 58°F to 125°F in the test. The median electric tankless model heats 0.7 gallons per minute by 67°F. Of 337 electric tankless models, 11 have a higher flow than this one.

In tests, 91% of the energy went to hot water, so its UEF is 0.91. Of the energy it spends heating water, 98% ends up in it (its recovery efficiency).
