1. A method of manufacture of a rigid heating panel comprising the steps of providing a continuous feed of a first sheet of material;continuously depositing a layer of settable gypsum slurry onto the first sheet of material in a continuous process to form a continuous open wallboard feed;continuously depositing at least one heating layer substantially along the length of the continuous open wallboard feed to at least partially embed in said settable gypsum slurry, said heating layer comprising: a heating element configured as a mesh, anda pair of electrical conductor members, said electrical conductor members being relatively more conductive than the heating element, and arranged to extend substantially parallel with the length direction of the continuous open wallboard feed;providing a continuous feed of a second sheet of material at an opposed side of the settable gypsum slurry to the first sheet of material to form a closed wallboard feed,and wherein the method further comprises the steps of:cutting the continuous closed wallboard feed to size, andallowing the settable gypsum slurry, with the heating layer at least partially embedded therein, to set in order to provide a self-supporting wallboard panel. 2. A method as claimed in claim 1, wherein the heating layer extends across substantially the entire width of the open continuous feed. 3. A method as claimed in claim 1, wherein the electrical conductor members are adapted to operate as busbars at terminal points along the edges of the heating element. 4. A method as claimed in claim 1, wherein the electrical conductor members are deposited to extend continuously along the sides of the length of the continuous open wallboard feed. 5. A method as claimed in claim 1, wherein the method includes the step of depositing at least one transverse conductor member, suitable for allowing termination of the heating panel at an opposed side of the heating panel from the heating element(s), along the length of the continuous open wallboard feed. 6. A method as claimed in claim 5, wherein the transverse conductor member is at least partially incorporated in the settable slurry layer. 7. A method as claimed in claim 5, wherein the transverse conductor member is set inside the settable slurry layer. 8. A method as claimed in claim 1, wherein the method includes sizing the closed wallboard feed by forcing the closed wallboard feed through a forming plate section. 9. A method as claimed in claim 1, wherein the electrical conductor member is prefabricated as a continuous sheet of at least partially conductive material. 10. A method as claimed in claim 1, wherein at least one selected from the first sheet of material and second sheet of material are composed of material that is at least partially porous to one or more selected from water vapour and liquid. 11. A method as claimed in claim 1, wherein at least one or more selected from the first sheet of material and second sheet of material are composed of paper. 12. A method as claimed in claim 1, wherein the electrical conductor members are composed of one or more selected from a metal or metallic alloy; a semi-conductor material; andcarbon fibre. 13.
