Noritz NRC111DV (GQ-C3257WX-FF US)
Noritz NRC111DV (GQ-C3257WX-FF US) is in the DOE listing as of Oct 26, 2026.
It has a certified UEF of 0.91 and a certified flow of 5.7 gal/min at a 67°F rise.
Its certified flow is 5.7 gal/min at a 67°F rise, while Noritz advertises 11.1 gal/min, no rise stated (Read Oct 5, 2026), so a comparison at the same rise is not possible.

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 5.5 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.
At a 67°F rise, its flow in the test is 5.7 gallons per minute. The median gas tankless model heats 4.8 gallons per minute by 67°F. Among 487 gas tankless models, 60 give more flow at a 67°F rise.
As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 91% of the energy it uses ends up as hot water (UEF 0.91). Its test simulated a day of high hot water use (its draw pattern). Its UEF is lower than that of 227 of the 399 gas tankless models with its draw pattern. A UEF of 0.93 is the median for its type and draw pattern. Of the energy it spends heating water, 94% ends up in it (its recovery efficiency).
Its test figures match those of one other basic model. That one carries the THERMALUX brand name.
It may qualify for 2 rebate programs in 2 states. Another 2 rebate programs may accept it if it meets their other terms.
