Abstract
A heating apparatus with automatic switching heaters includes a control module, a switch module, and a heating module. The control module receives an input power source. The switch module is connected to the control module. The heating module is connected to the switch module. When the control module detects that an amplitude of the input power source is larger than a threshold voltage value, the control module turns on a first switch assembly and turns off a second switch assembly of the switch module so that the heating module operates in a first heating mode. When the control module detects that the amplitude of the input power source is less than the threshold voltage value, the control module turns on the first switch assembly and the second switch assembly of the switch module so that the heating module operates in a second heating mode.
