This invention consists of a novel heat exchanger design and a novel means of its installation for Ground-Source Heat Pump Systems' ground heat gain/rejection loops. This improvement reduces the installation cost of such systems by method of placement and exchanger design. The Heat exchanger is a metal pipe, 20 to 40 feet long, approximately 1.25 to 2 inch diameter, containing an internal polymeric tube, installed in the pipe concentrically to carry the heat exchange medium from or to the bottom of the pipe; the pipe being inserted into the ground by means of a ballistic launcher or direct-push machine or by manual means. This system reduces the installation costs. The current art calls for extensive trenching or drilling, and yields high costs and detrimental impacts on property. This invention reduces surface impact areas. The only trenching connects the building to the tops of the Heat exchangers.
