Hydrothermal circuits

Hydrothermal circuits are systems that transfer heat by circulating water or other fluids through underground pathways or pipelines. These circuits are used to extract geothermal energy by capturing heat from beneath Earth's surface, or to distribute geothermal heat for heating buildings or industrial processes. Essentially, hot water or steam moves through a closed loop, carrying thermal energy from a heat source to where it’s needed, then returning to be reheated. This efficient circulation allows for sustainable, renewable energy use, minimizing environmental impact while providing a steady heat supply.
