Heater bundle for adaptive control

A heater system comprising:

• a heater bundle comprising:
• a plurality of heater assemblies, more than one of the heater assemblies comprising a plurality of heater units, more than one of the heater units defining at least one independently controlled heating zone, and
• a plurality of power conductors electrically connected to the independently controlled heating zones;
• means for determining at least one of heating conditions and heating requirements;
• and
• a power supply device including a controller configured to modulate power to the independently controlled heating zones of the heater units through the power conductors based on the at least one of heating conditions and heating requirements to provide a desired power output along a length of more than one of the heater assemblies.
