Hot Water List

Ruud RTG-84DVLN-3

Ruud RTG-84DVLN-3 is in the DOE listing as of Oct 19, 2026.

  • Gas tankless water heater
  • 2 listed models

Not listed as ENERGY STAR certified on Oct 19, 2026.

Its figures are also listed under Rheem RTG-84DVLN-3.

Certified figures

Flow at a 67°F rise

UEF
0.82Uniform energy factor

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 4.3 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 4.5 gallons per minute of water by 67°F in the test. The median flow among gas tankless models is 4.8 gallons per minute. Among 487 gas tankless models, 319 give more flow at a 67°F rise.

On Oct 19, 2026, this heater was not listed as ENERGY STAR certified. In the test, 18% of its energy does not reach the hot water (UEF 0.82). In the test, daily hot water use was set to high (its draw pattern). Of 399 gas tankless models with the same draw pattern, 243 have a higher UEF. For its type and draw pattern, the UEF runs from 0.81 to 0.98. Of the energy it spends heating water, 84% ends up in it (its recovery efficiency).

It is the basic model for RUTG-84DVLN-3 and RUTG-84DVLP-3. There are 4 more basic models with the same test figures. Each of them is listed under a different brand. You can find the whole group on the page for the Rheem RTG-84DVLN-3.
