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 4.7 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.
Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| RUTG-95XLN-1 | 0.81 | 4.9 | 83% | High |
| RUTG-95XLNWA-1 | 0.81 | 4.9 | 83% | High |
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 median flow among gas tankless models is 4.8 gallons per minute. Of 487 gas tankless models, 210 have a higher flow than this one.
On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 81% of the energy it uses ends up as hot water (UEF 0.81). The daily hot water use in the test, called its draw pattern, was high. Its UEF is lower than that of 327 of the 399 gas tankless models with its draw pattern. For its type and draw pattern, the median UEF is 0.93. While it heats water, 83% of the energy used goes into the water (its recovery efficiency).
It is the basic model for RUTG-95XLN-1 and RUTG-95XLNWA-1. There is one more basic model with the same test figures. The brand name on that one is Richmond. For the full group, see the Richmond RTG-95XLN-1.
