HEATING SYSTEM AND HEATER
An inductively power heating system includes an inductive power source for supplying power to an inductive heater. The inductive heater may include a resistive heater and a multiple coil secondary. A heater control within the inductive heater may control the power supplied to the resistive heater, and thereby control the temperature of the resistive heater. The inductive heater may encapsulate the resistive heater, the multiple coil secondary and the heater control, thereby providing a sealed, inductive heater.
