A heat collector system for heat supply of a heat pump system comprises a circuit flowed through by a liquid comprising a surface collector 6 and below this a collector 7 disposed deeply in the ground 10 in series with and downstream to the surface collector 6. The surface collector is conventional and is supplied with incident heat during the warm season, and supplies heat to the system during the warm season. The deep collector 7 delivers heat to the system during the cold season and is regenerated by the surface collector 6 during the warm season. <IMAGE> |
