Flow 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 5.5 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.

UEF is the uniform energy factor. A dash means the model has no such figure.

ENERGY STAR certified models

Midea MGWH199IXPP: ENERGY STAR certified models
Model number	UEF	Flow at a 67°F rise (gal/min)	Recovery efficiency

It heats 5.7 gallons per minute of water by 67°F in the test. The median gas tankless model heats 4.8 gallons per minute by 67°F. Of 487 gas tankless models, 60 have a higher flow than this one.

Under this basic model, 2 model numbers are ENERGY STAR certified. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). Its test ran at the high level of daily hot water use. Of 399 gas tankless models with the same draw pattern, 49 have a higher UEF and 217 a lower one. On its draw pattern, the median gas tankless UEF is 0.93. While it heats water, 99% of the energy used goes into the water (its recovery efficiency).

It is sold as JSG52-32PCHP-LP and MGWH199IXPP. All of its test figures are shared by 15 other basic models. Between them, those basic models carry 4 other brand names. For the full group, see the Elios EROD199N0000.

It may qualify for 6 rebate programs. Another 2 programs may accept it if it meets their other terms.
