Colder incoming water needs a bigger rise, so the heater gives 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 3.3 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 |
|---|---|---|---|---|
| A36TWH | 0.95 | 3.4 | 97% | — |
UEF is the uniform energy factor. A dash means the model has no such figure.
It heats 3.4 gallons per minute of water by 67°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Among 337 electric tankless models, 5 give more flow at a 67°F rise.
In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). When it runs, 97% of the energy it uses reaches the water (its recovery efficiency).
