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 5.3 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 |
|---|---|---|---|---|
| VRS-199 | 0.95 | 5.5 | 95% | High |
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 5.5 gallons per minute. The median gas tankless model heats 4.8 gallons per minute by 67°F. Among 487 gas tankless models, 92 give more flow at a 67°F rise.
On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In the test, 5% of its energy does not reach the hot water (UEF 0.95). Its test ran at the high level of daily hot water use. Of 399 gas tankless models with the same draw pattern, 49 have a higher UEF. For its type and draw pattern, the median UEF is 0.93. While it heats water, 95% of the energy used goes into the water (its recovery efficiency).
It may qualify for 2 rebate programs in 2 states. It may qualify for 2 more if it meets terms its figures do not show.
