Surface heating assembly and related methods

A method of forming a plurality of individual heating cables sets includes creating at least a portion of a master cable set by coupling alternating sections of cold and hot cable section, each section of cold cable section having a length twice a model cold cable section length and each section of hot cable section having a length twice a model hot cable section length. A continuous metallic ground sheath is applied about substantially all of the master cable set and a continuous outer jacket is applied about the continuous metallic ground sheath. The master cable set is segmented at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.
