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 5.5 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.

ENERGY STAR certified models
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency |
|---|---|---|---|
| S33-95TWH199-LP/NG | 0.95 | 5.7 | 99% |
At a 67°F rise, its flow in the test is 5.7 gallons per minute. The median flow among gas tankless models is 4.8 gallons per minute. Among 487 gas tankless models, 60 give more flow at a 67°F rise.
The single model number sold under it is ENERGY STAR certified. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). Its test simulated a day of high hot water use (its draw pattern). Its UEF is lower than that of 49 of the 399 gas tankless models with its draw pattern. For its type and draw pattern, the UEF runs from 0.81 to 0.98. When it runs, 99% of the energy it uses reaches the water (its recovery efficiency).
All of its test figures are shared by one other basic model.
