An analysis is presented of the performance of a coaxial heat exchanger used for the extraction of heat from a geothermal well, for use in space or process heating. The calculations are based on conductive heat transfer into the well and are therefore a lower bound on the performance of such a system, since in most cases heat will be transferred to the well convectively. The analysis makes use of full solution to the problem including temperature variation with depth, transfer between inner and outer tubes, friction and the cooling of the formation with time.
