In the embodiment illustrated in FIG. 8, the graphite element 804 may efficiently convert energy across a wider surface area than may be available with conventional resistive elements 208. For example, a graphite element configured to draw 6 Amps of current may provide 780 Watts of thermal power evenly across a 23 foot by 12 foot cover surface area. Such a configuration provides sufficient heat energy to maintain a temperature between 50 degrees Fahrenheit, and 90 degrees Fahrenheit, in freezing ambient conditions. Additionally, using such a configuration, it is possible to connect up to three modular thermal covers on a single 120 Volt power source protected by a single 20 Amp circuit. Thus, consistent heat may be provided for between about 300 to about 1000 square feet of surface on a single 20 Amp power source.
