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 4.1 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 |
|---|---|---|---|---|
| VRP-150 | 0.95 | 4.3 | 97% | High |
UEF is the uniform energy factor. A dash means the model has no such figure.

| Model number | UEF | Flow at a 67°F rise (gal/min) |
|---|---|---|
| VRP-150 | 0.95 | 4.3 |
At a 67°F rise, its flow in the test is 4.3 gallons per minute. The gas tankless type has a median flow of 4.8 gallons per minute. Its flow at a 67°F rise trails 346 of the 487 gas tankless models.
It is ENERGY STAR certified under its single model number. In tests, 95% of the energy went to hot water, so its UEF is 0.95. In the test, daily hot water use was set to high (its draw pattern). Of 399 gas tankless models with the same draw pattern, 49 have a higher UEF. A UEF of 0.93 is the median for its type and draw pattern. Of the energy it spends heating water, 97% ends up in it (its recovery efficiency).
In 7 states, 6 rebate programs may accept it. It may qualify for 2 more if it meets terms its figures do not show.
