Comparison of pressures in the N–S section through the Buntsandstein aquifer at the end of a 175 d storage cycle (A) and heating cycle (B) based on varying injection rates of 5, 10, 20, 30, and 40 L s−1. Comparison of long-term behavior of differential pressures in the Buntsandstein aquifer over 10 storage and heating cycles at wells BS-North (C) and BS-South (D) based on varying injection rates of 5, 10, 20, 30, and 40 L s−1
