| Abstract | A novel form of ground heat exchanger (GHE) for use in GSHP applications is described. Known as a Thermo Screw PileTM (TSP), it is an extension to the use of mechanical screw piles that are already being deployed as a rapid, clean, concrete-free, low-carbon method of building foundation installation. By adapting the steel screw pile to become a GHE as well, a closed-loop ground collector installation can be achieved by interconnecting a number of TSPs. The solution is quicker to install and significantly less costly than an equivalent borehole installation. The paper presents the concept and explores the evolution of the TSPs and comments on the potential range of applications to which TSPs may be applied. |
