Bradford White CTEH018********

Bradford White CTEH018******** is in the DOE listing as of Oct 26, 2026.

It has a certified UEF of 0.96 and a certified flow of 1.8 gal/min at a 67°F rise.

  • Electric tankless water heater
  • 2 listed models

ENERGY STAR certification does not cover this type of 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 1.7 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 1.8 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. Of 337 electric tankless models, 33 have a higher flow than this one.

In the test, 4% of its energy does not reach the hot water (UEF 0.96). When it runs, 98% of the energy it uses reaches the water (its recovery efficiency).

It is sold as CTEH018******** and CTEV018********. There are 3 more basic models with the same test figures. Those basic models are sold with ECOSMART and Laars as their brand names.
