Abstract
Deep borehole heat exchangers are an environmentally advantageous way for geothermal energy production. The weakness of this proposed production technology is the moderate temperature of the outflowing water and the relatively low thermal power. During the initial period of the operation both the temperature and the power has a higher value, but they tend a lower equilibrium value. This is the sustainable production of the system. Seminumerical simulation is used to determine this limit.
