Systems and methods for temperature sensing in a deicer

A deicer system for heating water within a fluid receptacle to prevent ice from forming, the system comprising:

• a main body configured to be positioned within the fluid receptacle;
• a heating element adapted to heat the water, wherein said heating element is supported by said main body;
• a plurality of temperature sensors adapted to detect a temperature, wherein said plurality of temperature sensors are thermally connected to said heating element through at least one heat path element, wherein at least one of said plurality of temperature sensors includes one or more of a thermistor, thermocouple, resistance temperature detector, thermometer, or silicon bandgap temperature sensor;
• and
• a control unit in communication with said heating element and said plurality of temperature sensors, wherein said control unit includes one or more of a processor, a microprocessor, an integrated circuit, or a plurality of discrete logic components, wherein said control unit is adapted to determine a temperature of the water based at least in part on the temperature detected by said plurality of temperature sensors, and wherein said control unit is adapted to control said heating element based at least in part on the determined temperature of the water.
