A system for a low-energy network includes a collector circuit (1a, 1b) filled with a first transfer solution, a heat transfer circuit (7) filled with a second transfer solution, and a terminal (3) adapted to transfer heat between the transfer solutions of the collector circuit (1a, 1b) and the heat transfer circuit (7). The collector circuits (1a, 1b) are connected to the terminal via two distribution reservoirs (82, 81), of which the first distribution reservoir (81) is isolated and configured to receive and transfer heated transfer liquid, and the second distribution reservoir (82) is configured to receive and transfer cooled transfer liquid, and at least one collector circuit (1a, 1b) connecting the first distribution reservoir (81) and the second distribution reservoir (82) is connected to each distribution reservoir (81, 82) terminating the low-energy network. The system may also include a distribution tank (80) for the low-energy network.
