Particular embodiments generally relate to a heating cable that includes a plurality of bus wires positioned on the outside of a heating element. In one embodiment, a spacer is provided. A heating element is included on a surface of the spacer. The heating element also includes one or more resistance wires. A plurality of bus wires are positioned on the edges of the spacer that has the heating element wrapped around it. For example, a first bus wire is positioned on a first side of the spacer and a second bus wire is positioned on a second side of the spacer. A plurality of node areas (e.g., on the bus wires or on an insulated heating element) allow a resistance wire of the heating element to be electrically coupled to the bus wires at the plurality of node areas on alternating bus wires.
