1. A heating system comprising:
a support structure having a plurality of projections formed thereon; and
a heating wire;
wherein the plurality of projections form a first set of substantially parallel undulating channels on the support structure, the undulations of each channel being formed by a series of constrictions that are alternately offset in opposite directions along a length of the respective channel;
wherein the heating wire is configured to be retained within one or more of the substantially parallel undulating channels formed on the support structure;
wherein the heating wire undulates within the one or more of the substantially parallel undulating channels when the heating wire is retained therein;
wherein each undulation of each of the substantially parallel undulating channels has an amplitude that does not exceed a width of the respective channel;
wherein the projections of the plurality of projections are grouped into pairs;
wherein each pair of projections has one of two orientations, one orientation being a ninety degree rotation of the other orientation;
wherein the pairs of projections are arranged on the support structure in a rectangular grid with the orientations of the pairs of projections being set according to a checkerboard pattern;
wherein, in a first one of the two orientations, the pairs of projections form a structure that is wider in a first dimension than in a second, perpendicular dimension; and
wherein, in a second one of the two orientations, the pairs of projections form a structure that is wider in the second dimension than in the first dimension.
