A network control electric fireplace includes a housing, an image screen in the housing, an imitation charcoal, an illuminating device, a flame processing device, a light reflection device, an image light source, a heater, and a control device. The light reflection device includes a light reflection assembly and a motor. The control device is used to receive the network control command sent from the electronic apparatus. The heater, the illuminating device, the motor, and the image light source are connected with the control device, such that each function of the electric fireplace can be achieved by the network control. In winter, the user can turn on the heater through network control to warm up the indoor in advance, such that he/she can feel warm air indoors. It is not required to operate the operation panel on the electric fireplace. It is convenient to operate and use the present invention.

A heating device is provided. A temperature sensing unit is configured to sense an ambient temperature and accordingly output a temperature sensing voltage. A driving unit is coupled to a heating transistor unit and the temperature sensing unit, and configured to drive the heating transistor unit for performing heating based on the temperature sensing voltage. An activating unit is coupled to the temperature sensing unit, configured to output an activating signal based on the temperature sensing voltage when a temperature of the printed circuit board has risen up to a preset temperature. The heating device as provided can assure that the activating signal can be normally outputted by the heating device under an ambient at an extremely low temperature.
