A liquid jetting apparatus includes a first head unit and a second head unit, each of the head units including nozzles through which a liquid is discharged; a head drive section configured to drive the first head unit and the second head unit; a controller configured to control the head drive section to selectively execute a first drive mode in which both of the first head unit and the second head unit are driven and a second drive mode in which only the second head unit is driven; and a heating element configured to generate heat under a condition that the head drive section executes the first drive mode and the second drive mode. The second head unit is arranged at a position separated farther from the heating element than the first head unit.
