Abstract
A method and device for installing a tube of a geothermal closed loop system in the ground. A drill rod includes a hook for removably mounting the heat exchange tube for positioning the tube in the hole bored in the ground by the drill bit. The tube may be inserted into the bored hole once the drill is removed therefrom, mounted to the tube and then reinserted into the hole. Alternatively, the tube is mounted to the drill rod as the hole is being bored.
