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 0.9 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

|---|---|---|---|---|
| RTEH95T | 0.98 | 0.9 | 98% | 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 0.9 gallons per minute. The median flow among electric tankless models is 0.7 gallons per minute. Its flow at a 67°F rise trails 114 of the 337 electric tankless models.
In the test, 2% of its energy does not reach the hot water (UEF 0.98). Its test simulated a day of very small hot water use (its draw pattern). Its UEF is lower than that of 10 of the 272 electric tankless models with its draw pattern. On its draw pattern, the median electric tankless UEF is 0.96. While it heats water, 98% of the energy used goes into the water (its recovery efficiency).
All of its test figures are shared by 5 other basic models. The EEMAX and KWICKSHOT brands list one or more of them. For the full group, see the Rheem SPEX90T.
