Change your hour and flowFlow where you live
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 0.7 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 |
|---|---|---|---|---|
| SPEX75T | 0.97 | 0.7 | 97% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It heats 0.7 gallons per minute of water by 67°F in the test. The median flow among electric tankless models is 0.7 gallons per minute. Of 337 electric tankless models, 154 have a higher flow than this one.
In tests, 97% of the energy it uses ends up as hot water (UEF 0.97). In the test, daily hot water use was set to very small (its draw pattern). Of 272 electric tankless models with the same draw pattern, 37 have a higher UEF and 195 a lower one. For its type and draw pattern, the median UEF is 0.96. When it runs, 97% of the energy it uses reaches the water (its recovery efficiency).
Its test figures match those of 2 other basic models. Those basic models are sold with KWICKSHOT and Rheem as their brand names. For the full group, see the Rheem SPEX75T.
