· extra resistance to heat flow due to the presence of a concrete layer around the heat carrying pipe is negligibly small compared to the total heat resistance. The rate of heat or cold extraction of a single energy pile depends primarily on the temperature of the heat carrying fluid and the heat conductivity of the soil surrounding the pile.
