Conductive core contains flammable materials.
Covering the cable prevents it from becoming trapped in the insulation. Use wire, pre-punched strapping, or aluminum or fiberglass tape to fasten the cable to the tank. Multiply the diameter of the tank by the height. This gives you the area of the cylindrical surface. Divide the diameter by 2, then square the result.
