Change your hour and flowFlow where you live
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 3.7 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 |
|---|---|---|---|---|
| RA65LH, RA65SH, RA65ZH | 0.82 | 3.9 | 84% | Medium |
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 3.9 gallons per minute. The median flow among gas tankless models is 4.8 gallons per minute. Of 487 gas tankless models, 399 have a higher flow than this one.
On Oct 19, 2026, this heater was not listed as ENERGY STAR certified. In the test, 18% of its energy does not reach the hot water (UEF 0.82). Its test ran at the medium level of daily hot water use. Among 77 gas tankless models on its draw pattern, 30 have a higher UEF. For its type and draw pattern, its UEF sits at the median. When it runs, 84% of the energy it uses reaches the water (its recovery efficiency).
Its test figures match those of 2 other basic models. Of those, one or more are under the eyoo brand. You can find the whole group on the page for the eyoo EA65EH.
It may qualify for one rebate program if it meets terms its figures do not show.
