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 3.8 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-70DVLN-3 | 0.82 | 4.0 | 84% | High |
| RUTG-70DVLP-3 | 0.82 | 4.0 | 84% | High |
| RUTG-R70DVELN-3 | 0.82 | 4.0 | 84% | High |
| RUTG-R70DVELP-3 | 0.82 | 4.0 | 84% | High |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 4.0 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, 385 have a higher flow than this one.
As of Oct 19, 2026, it was not listed as ENERGY STAR certified. In tests, 82% of the energy went to hot water, so its UEF is 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 and 72 a lower one. For its type and draw pattern, the median UEF is 0.93. When it runs, 84% of the energy it uses reaches the water (its recovery efficiency).
A tag or quote may show any of its 4 model numbers. There are 8 more basic models with the same test figures. Between them, those basic models carry 4 other brand names. For the full group, see the Rheem RTG-70DVLN-3 page.
