Paragraph Number

14

In one further embodiment, the electrical heating element may comprise a resistive element for converting electric current to heat energy and a substantially planar heat spreading element for distributing the heat energy generated by the resistive element. In one embodiment, the electrical heating element generates substantially consistent levels of thermal energy across the surface area of the thermal cover. Additionally, the thermal cover may comprise at least one receiving power coupling and at least one conveying power coupling. In one embodiment, the conveying power coupling of a first modular heated cover can be optionally or removably coupled to the receiving power coupling of a second modular heated cover such that the first modular heated cover and second modular heated cover draw electricity from a single circuit providing up to about 120 Volts. The single circuit is preferably protected by up to about a 20 Amp breaker. In certain embodiments, the electrical heating element is configured such that the electrical heating element has a negative temperature coefficient of resistance.
