Abstract
Two or more reversible wells open respectively into a "hot" zone and a "cold" zone of a reservoir or captive layer. The water of the layer is circulated within a primary circuit in a first direction corresponding to circulation within an external loop from the "cold zone" wells to the "hot zone" wells and in a second direction corresponding to circulation from the "hot zone" wells to the "cold zone" wells. Indirect heat transfer takes place between the primary circuit and a secondary heating circuit in the first direction or between the primary circuit and a secondary utilization circuit in the second direction, the flow rate within the primary circuit being regulated in both directions.
