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 5.0 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 |
|---|---|---|---|---|
| MGWH180IXPN | 0.95 | 5.2 | 99% | High |
UEF is the uniform energy factor. A dash means the model has no such figure.
ENERGY STAR certified models
| Model number | UEF | Flow at a 67°F rise (gal/min) |
|---|---|---|
| MGWH180IXPN | 0.95 | 5.2 |
At a 67°F rise, its flow in the test is 5.2 gallons per minute. The gas tankless type has a median flow of 4.8 gallons per minute. Its flow at a 67°F rise trails 145 of the 487 gas tankless models.
The single model number sold under it is ENERGY STAR certified. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). Its test simulated a day of high hot water use (its draw pattern). Among 399 gas tankless models on its draw pattern, 49 have a higher UEF. For its type and draw pattern, the UEF runs from 0.81 to 0.98. When it runs, 99% of the energy it uses reaches the water (its recovery efficiency).
All of its test figures are shared by 8 other basic models. The Elios and Kepler brands list one or more of them. For the full group, see the Elios EROD180N0000.
