Systems for coupling ends of elongated heaters and methods of using such systems to treat a subsurface formation are described herein. A system may include two elongated heaters with an end portion of one heater abutted or near to an end portion of the other heater and a core coupling material. The core coupling material may extend between the two elongated heaters. The elongated heaters may include cores and at least one conductor substantially concentrically surrounds the cores. The cores may have a lower melting point than the conductors. At least one end portion of the conductor may have a beveled edge. The gap formed by the beveled edge may be filled with a coupling material for coupling the one or more conductors. One end portion of at least one core may have a recessed opening and the core coupling material may be partially inside the recessed opening.

1. A system for coupling ends of elongated heaters, comprising: two elongated heaters with an end portion of a first heater abutted or near to an end portion of a second heater, the elongated heaters comprising cores and one or more conductors substantially concentrically surrounding the cores, the cores having a lower melting point than the conductors, at least one end portion of at least one conductor of the first heater having a beveled edge that forms a gap between the beveled edge and an end portion of at least one conductor of the second heater, and wherein at least one end portion of at least one core has a recessed opening;a core coupling material at least partially inside the recessed opening, the core coupling material extending between the two elongated heaters; andwherein the gap formed by the beveled edge is configured to be filled with a coupling material for coupling the one or more conductors. 2. The system of claim 1, wherein the end portion of the conductor of the second heater has a beveled edge. 3. The system of claim 1, wherein the end portions of both cores have recessed openings. 4. The system of claim 1, wherein the core comprises copper. 5. The system of claim 1, wherein the core coupling material comprises copper. 6. The system of claim 1, wherein at least one conductor comprises ferromagnetic material. 7. The system of claim 1, wherein the outermost conductor comprises stainless steel. 8. The system of claim 1, wherein the coupling material comprises a non-ferromagnetic material. 9. The system of claim 1, wherein the core coupling material comprises material that thermally expands radially more than the coupling material. 10. The system of claim 1, wherein the elongated heaters comprise cores substantially concentrically surrounded by ferromagnetic conductors, the ferromagnetic conductors substantially concentrically surrounded by an outer electrical conductor. 11. The system of claim 1, wherein the elongated heaters are configured to be coupled by welding together the conductors with the coupling material in the gap formed by the beveled edge. 12. The system of claim 1, wherein electrical current is configured to flow primarily through the core coupling material when an electrical current is applied to the elongated heaters. 13. The system of claim 1, wherein the heaters are configured to be used to heat a subsurface formation. 14. A method for coupling two elongated heaters, comprising: placing a core coupling material in recesses in the end portions of cores of the two elongated heaters, the cores of the heaters substantially concentrically surrounded by one or more conductors, the cores having a lower melting point than the one or more conductors; andcoupling the end portions of the two heaters by filling gaps between beveled edges of the end portions of the one or more conductors with a coupling material. 15. The method of claim 14, further comprising coupling the end portions of the two heaters by welding together the end portions. 16. The method of claim 14, wherein the coupling material comprises non-ferromagnetic material. 17. The method of claim 14, wherein the core coupling material comprises copper. 18. The method of claim 14, wherein during coupling of the end portions of the two heaters, electricity primarily flows through the core coupling material. 19. The method of claim 14, wherein the two heaters are coupled without welding the cores of the heaters together. 20. The method of claim 14, further comprising installing the heaters in a subsurface formation. 21. The method of claim 14, further comprising applying electrical current to the heaters, and providing heat from the heaters to at least a portion of a subsurface formation.
