Apparatus, system, and method for controlling a molten salt heat exchanger. The system includes a magma-driven heat exchanger extending at least partially within a magma body containing magma. Molten salt flowing through the magma-driven heat exchanger absorbs heat from the magma to form a heated molten salt. A second heat exchanger disposed external to the magma-driven heat exchanger uses the heated molten salt to heat a working fluid from a first temperature to a second temperature higher than the first temperature. The system also includes a set of fluid conduits forming a flow path that transports the molten salt in a loop between the magma-driven heat exchanger and the second heat exchanger. A fluid control device is included for controlling the flow of the molten salt through the flow path.
