A conduit adapted for use as a subterranean geothermal heat exchanger, the conduit comprises: a. a twisted pipe arrangement that includes a central pipe, said central pipe is open-ended, said central pipe does not convey heat exchange fluid the central pipe centrally located in the twisted pipe arrangement;b. two or more outer pipes included in the twisted pipe arrangement, the two or more outer pipes in a twisted pipe configuration around said central pipe, said two or more outer pipes adapted to convey heat exchange fluid, said two or more outer pipes include at least one in-flow pipe and at least one out-flow pipe, said twisted pipe arrangement includes the two or more outer pipes separated and said two or more pipes touch the central pipe, said two or more outer pipes twisted around said central pipe configured for transportation and insertion, said twisted pipe configuration of the two or more outer twisted pipes configured-to exchange heat with the external environment; andc. a fitting, said two or more outer pipes direct the flow of said heat exchange fluid from said at least one in-flow pipe to said at least one out-flow pipe, the fitting connects the at least one in-flow pipe and the at least one out-flow pipe, the twisted pipe arrangement inserted in the ground, the two or more outer pipes in the twisted pipe configuration of twisted pipes inserted in the ground and transfers heat with the ground in the twisted pipe arrangement, wherein the twisted pipe arrangement includes a helical twist, the two or more outer pipes separated from another, the central pipe has a twisting configuration that includes a helical twist at an acute angle relative to a central axis of the twisted pipe arrangement located in the ground. 2. The conduit of claim 1, wherein said two or more outer pipes are arranged to be separated by a spacing member. 3. The conduit of claim 2, wherein said spacing member is an insulator. 4. The conduit of claim 1, wherein said pipes are constructed from plastic materials including polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), fibre reinforced plastic (FRP), reinforced polymer mortar (RPMP), polypropylene (PP), polyethylene (PE), high density polyethylene (HDPE), cross-linked high-density polyethylene (PEX), polybutylene (PB), and acrylonitrile butadience styrene (ABS), and PEX/Aluminum/PEX. 5. The conduit of claim 1, wherein the fitting is a U bend that connects each at least one in-flow pipe and at least one out-flow pipe. 6. The conduit of claim 1, wherein the two or more outer pipes twisted around the central pipe is positionable in a roll for transportation and the two or more outer pipes twisted around the central pipe are configured for installation into a borehole, the central pipe a grout pipe. 7. The conduit of claim 1, wherein the central pipe is an open ended central pipe and the two or more outer pipes twisted around said central pipe are pre-fabricated as the twisted pipe arrangement, the twisted pipe arrangement is configured for transportation and installed as the twisted pipe arrangement for geothermal heat exchange. 8. The conduit of claim 1, wherein the at least one in-flow pipe includes multiple in-flow pipes and the at least one out-flow pipe includes multiple out-flow pipes and the in-flow pipes are grouped together and the out-flow pipes are grouped together. 9. A conduit for use as a geothermal heat exchanger, the conduit comprises: a twisted pipe arrangement that includes a central pipe, the central pipe is open ended; andtwo or more pipes included in the twisted pipe arrangement, the two or more pipes twisted, at least one of the two or more pipes arranged to touch the central pipe and said two or more pipes arranged to be separated, said two or more pipes include at least one in-flow pipe and at least one out-flow pipe, the two or more pipes twisted around the central pipe, the central pipe is centrally located in the twisted pipe arrangement and the two or more pipes twisted around the central pipe as a pre-fabricated twisted conduit and the pre-fabricated twisted conduit has a pre-fabricated twisted pipe configuration of the two or more pipes around the central pipe, the two or more pipes are outer pipes, the two or more outer pipes twisted around the central pipe,the conduit as the pre-fabricated twisted pipe arrangement arranged for transportation in a roll, the twisted pipe arrangement includes the two or more outer pipes and the central pipe, the twisted pipe arrangement inserted in the ground in the twisted pipe configuration of the two or more outer pipes around the central pipe, the pre-fabricated twisted pipe arrangement transfers heat between the outer pipes and the ground using the same twisted pipe configuration of the two or more pipes of the pre-fabricated twisted pipe arrangement, wherein the twisted pipe arrangement includes a helical twist, the two or more outer pipes separated from one another, the central pipe has a twisting configuration that includes a helical twist at an acute angle relative to a central axis of the twisted pipe arrangement located in the ground. 10. The conduit of claim 9 that further includes a spacing member and the spacing member separates the at least one in flow and the at least one out flow pipes. 11. The conduit of claim 9 that further includes a spacing member and the spacing member separates each pipe of the two or more outer pipes. 12. The conduit of claim 9, wherein the two or more outer pipes further include at least one fitting that connects the at least one inflow pipe and the at least one out flow pipe. 13. The conduit of claim 9, wherein the twisted pipe arrangement of the two or more pipes and central pipe is pre-fabricated and rolled up for transportation and the twisted pipe arrangement is unrolled and installed in the ground and the two or more pipes of the twisted pipe arrangement installed in ground arranged for geothermal heat exchange as the pre-fabricated twisted assembly. 14. The conduit of claim 9, wherein the central pipe is a centrally positioned grout pipe and the two or more pipes are outer pipes twisted around the central pipe. 15. The conduit of claim 9, wherein the central pipe is a heat transfer insulator. 16.
