Long-term behavior of the aquifer temperature in close vicinity of the wells BS-North (red) and BS-South (blue) at 3 different heat extractions in the heating cycle. Flow rate (Q = 10 L s−1) and injection temperature (80 °C) during storage cycle are constant. At the ‘hot side’ of the aquifer storage temperature is increasing with each cycle (red). Influence of storage efficiency on the ‘cold side’ of the aquifer storage is shown by 3 scenarios (A, B, C)
