AbstractThis paper describes a novel horizontal ground heat exchange system used in an experimental Ground Source Heat Pump ( GSHP) installation. The basic concept is to activate a large mass of soil by employing "large" (up to 60 cm) spiral heat exchangers made of copper and high density polyethylene tubing. The results of monitoring the system during the 1988/90 winter season demonstrate its excellent performance. In addition, these results together with our experience, indicate that large potential savings on initial installation costs are possible. Moreover, such horizontal systems may be more economical than vertical GSHP systems in most practical situations.
