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 0.4 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 |
|---|---|---|---|---|
| TEF041V277 | 0.96 | 0.4 | 96% | Very small |
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 0.4 gallons per minute. The median electric tankless model heats 0.7 gallons per minute by 67°F. Among 337 electric tankless models, 233 give more flow at a 67°F rise.
In tests, 96% of the energy it uses ends up as hot water (UEF 0.96). Its test simulated a day of very small hot water use (its draw pattern). Of 272 electric tankless models with the same draw pattern, 77 have a higher UEF. On its draw pattern, its UEF is also the median electric tankless UEF. Of the energy it spends heating water, 96% ends up in it (its recovery efficiency).
There are 2 more basic models with the same test figures. The EEMAX and Rheem brands list one or more of them. For the full group, see the Rheem SPEX4277 page.
