Change your hour and flowFlow where you live
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 1.0 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 |
|---|---|---|---|---|
| LCTEH010******** | 0.91 | 1.0 | 93% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It warms 1.0 gallons per minute of water from 58°F to 125°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Its flow at a 67°F rise trails 91 of the 337 electric tankless models.
In tests, 91% of the energy it uses ends up as hot water (UEF 0.91). The daily hot water use in the test, called its draw pattern, was very small. Of 272 electric tankless models with the same draw pattern, 265 have a higher UEF. A UEF of 0.96 is the median for its type and draw pattern. When it runs, 93% of the energy it uses reaches the water (its recovery efficiency).
Its test figures match those of 2 other basic models. Of those, one or more are under the Bradford White brand. For the full group, see the Bradford White CTEH010********.
