Two different types of ground heat store have been investigated in the study. One store is based on a conventional technique, similar to the construction of ground heat stores in rock. The second type of ground heat store is a combination of a water filled pit and a ground heat store with a horizontal duct system. The first store is constructed by drilling wells and the second by excavating, lining, duct system installation and gradual refilling of the excavated soil.
