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 5.4 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.
Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| RUTGH-C95XLN | 0.93 | 5.6 | 95% | High |
| RUTGH-CM95XLN | 0.93 | 5.6 | 95% | High |
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 5.6 gallons per minute. The median gas tankless model heats 4.8 gallons per minute by 67°F. Its flow at a 67°F rise trails 86 of the 487 gas tankless models.
As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 93% of the energy it uses ends up as hot water (UEF 0.93). Its test ran at the high level of daily hot water use. Of 399 gas tankless models with the same draw pattern, 196 have a higher UEF. On its draw pattern, its UEF is also the median gas tankless UEF. When it runs, 95% of the energy it uses reaches the water (its recovery efficiency).
It is sold as RUTGH-C95XLN and RUTGH-CM95XLN.
