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 5.6 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.
ENERGY STAR certified models
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency |
|---|---|---|---|
| VRS PLUS-199 | 0.96 | 5.9 | 99% |
It heats 5.9 gallons per minute of water by 67°F in the test. The gas tankless type has a median flow of 4.8 gallons per minute. Of 487 gas tankless models, 17 have a higher flow than this one.
It is ENERGY STAR certified under its single model number. In the test, 4% of its energy does not reach the hot water (UEF 0.96). Its test ran at the high level of daily hot water use. Of 399 gas tankless models with the same draw pattern, 15 have a higher UEF and 350 a lower one. A UEF of 0.93 is the median for its type and draw pattern. While it heats water, 99% of the energy used goes into the water (its recovery efficiency).
Its test figures match those of one other basic model.
It may qualify for 6 rebate programs. It may qualify for 2 more if it meets terms its figures do not show.
