Certain embodiments of the present invention provide a deicer system for heating water within a fluid receptacle to prevent ice from forming, the system including a main body configured to be positioned within the fluid receptacle, a heating element adapted to heat the water, a temperature sensor adapted to detect a temperature of the water, a switch adapted to activate and deactivate the heating element, and a control unit in communication with the heating element, the temperature sensor, and the switch. The heating element is supported by the main body. The control unit is adapted to control the heating element using the switch based at least in part on a temperature detected by the temperature sensor.
