In addition, the thermal conductance of the rocks (changing as the rock minerals change with deeper depths), the area heat flow, and the rock density (sedimentary rocks are less dense than basement rocks) are used to calculate the deeper temperatures. Most of the measured temperatures used in the calculations are from sedimentary rocks which overlie the harder basement rock. total length of the earth-coupled heat exchanger per 10 tons of load for for finding this.
