Design information (cont.) Geothermal collector The thermal properties of the upper layer of the earth, such as the volumetric thermal capacity and thermal conductivity, are largely dependent on the consistency and properties of the ground. The wetter the soil, the higher the proportion of mineral constituents (quartz or feldspar) of the soil and the smaller the proportion of pores, the better the storage characteristics and thermal conductivity.
