In Scandinavia, there are more than 3,000 soccer fields with artificial turf. About 300 of these have subsurface hydronic heating systems. The heated turfs make it possible for training and games throughout most of the year. Furthermore, a pitch that is kept frost-free prevents injuries caused by slippery turf and frozen ground conditions. Practically all heated soccer fields in Scandinavia use district heating as a heat source. Only a few fields are using ground source heat pump systems (GSHP). However, the potential for a more extensive use of GSHP systems seems promising due to the considerably lower energy cost. In this paper, the use of GSHPs for subsurface heating of soccer fields with artificial turf is analyzed in terms of design, functional characteristics, and energy cost saving. Finally, aspects of market conditions for broader use of GSHP systems for these applications are given, focused on the Scandinavian countries.
