TITLE HORIZONTAL SPIRAL GROUND HEAT EXCHANGER INVENTOR Otto J. Svec A horizontal ground heat exchange system employing the natural thermal qualities just below the earth surface, comprising an elongated horizontal trench and a coil of high density elastomeric material horizontally inserted into an elongated horizontal trench. The coil is connected at one end by inlet tubing to an open holding tank and at the other end by return tubing connected to the heat pump unit. The entire coil is preferably enclosed in sand and backfill may be inserted in the horizontal trench to achieve ground level. A brine solution is passed through the system to transfer the thermal energy to or from the heat pump system.
