To provide effective usage of an energy system method not causing environmental pollution to the earth by digging for providing hot spring heat, and introducing a circulation system method in a heating system/hot water heating system device of hot spring heat/earth water hardly expected to be exhausted.

In a device/system regarding circuit circulation, the heating system and hot water heating system using hot spring heat by utilization of hot spring heat/earth water at a global scale is the ultimate solution as long as there is earth.
