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 4.5 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 |
|---|---|---|---|
| VTP-150 | 0.96 | 4.7 | 99% |
It heats 4.7 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. Among 487 gas tankless models, 252 give more flow at a 67°F rise.
Its single model number, VTP-150, is ENERGY STAR certified. 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. Among 399 gas tankless models on its draw pattern, 15 have a higher UEF. A UEF of 0.93 is the median for its type and draw pattern. When it runs, 99% of the energy it uses reaches the water (its recovery efficiency).
