1. An infrared heating panel, comprising:

  • a first power density zone;

    a second power density zone;

    an electrically insulative planar substrate;

    a plurality of infrared heating elements carried by the substrate, each heating element comprising a first end, a second end, and an elongated segment extending between the first end and the second end; and

    at least a first power bus and a second power bus, each of the first and the second power buses extending perpendicularly across and electrically connecting with each of the plurality of heating elements;

    wherein the first power bus is electrically connected to the elongated segments between the first end and the second end of each of the heating elements; and

    wherein the elongated segment of each heating element comprisesan electrically resistive material adapted to emit infrared radiation in response to a current flow,a first segment portion extending into the first power density zone between the first power bus and the first end of the heating element, the first segment portion configured to generate a first power density in response to a current flow, anda second segment portion extending into the second power density zone between the first power bus and the second end of the heating element, the second segment portion configured to generate a second power density in response to a current flow, the second power density being separate from the first power density.
