BTES heat extraction efficiency increases with decreasing soil thermal conductivity. BTES efficiency decreases with convective heat losses associated with high soil permeability.

While the heat storage in energy pile groups in unsaturated soil layers was always between that of dry and saturated soils with no groundwater flow, the soil hydraulic properties and water table depth were found to control both the rate of heat transfer and the total heat stored.
Borehole thermal energy storage systems are probably located in unsaturated zones, in part to take advantage of the lower thermal conductivity with degree of saturation (Smits et al., 2013).
While boreholes in rock extending to up to 1000 m have been studied for thermal energy storage (e.g., ), most thermal energy storage systems involve boreholes in soil with lengths on the order of 50 m and spacing between 1.5 and 3.0 m.
