Beneficially, the apparatus 600 provides high versatility for power connections, provides variable heat intensity levels, and the like. For example, the first active electrical heating element 608 and the second active electrical heating element 610 may be configured within the thermal cover 200 at a spacing of four inches. In one embodiment, the first active electrical heating element 608 and the second active electrical heating element 610 connect to a hot and a neutral power line. The electrical heating elements may be positioned within the thermal cover 200 in a serpentine configuration, an interlocking finger configuration, a coil configuration, or the like. When the 120V plug 602 is connected, only the first active electrical heating element 608 is powered. When the 240V plug 604 is connected, both the first active electrical heating element 608 and the second active electrical heating element 610 are powered. Therefore, the resulting effective spacing of the electrical heating elements is only four inches.
