A bigger rise from colder incoming water leaves the heater with 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 4.7 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 4.9 gallons per minute of water from 58°F to 125°F in the test. The gas tankless type has a median flow of 4.8 gallons per minute. Of 487 gas tankless models, 210 have a higher flow than this one.
It was not listed as ENERGY STAR certified on Oct 19, 2026. In tests, 93% of the energy went to hot water, so its UEF is 0.93. The daily hot water use in the test, called its draw pattern, was high. Its UEF is lower than that of 196 of the 399 gas tankless models with its draw pattern. On its draw pattern, its UEF is also the median gas tankless UEF. Of the energy it spends heating water, 94% ends up in it (its recovery efficiency).
It is the basic model for RMTGH90DVELN-3 and RMTGH90DVELP-3. Its test figures match those of 3 other basic models. Of those, one or more are under the Friedrich, Rheem, and Ruud brands. You can find the whole group on the page for the Rheem RTGH-90DVLN-3.
It may qualify for 2 rebate programs in 2 states. Another 2 programs may accept it if it meets their other terms.
