An arrangement for effecting an energy exchange between earth soil and an energy exchanger, and including a soil heat exchanger, and supply and return flow conduits for connecting the soil heat exchanger with the energy heat exchanger, with the soil heat exchanger having a thermoinsulated supply pipe arranged in a borehole formed in ground, a pump provided at an end of the flow duct, a shroud pipe surrounding the flow duct and the pump and having a section with a reduced inner cross- sectional area located beneath the pump and provided with a plurality of lateral inlet openings, and a return flow region for return water located radially outwardly of the shroud pipe and including return flow pipe means, connectable with the return flow conduit, and a porous filling, the return flow region communicating, in the vicinity of a borehole bottom, with an interior of the shroud pipe through the lateral inlet openings provided in the shroud pipe section with a reduced inner cross- sectional area.
