Comparison of temperature changes in a horizontal section through the aquifer at the end of a 175 d storage cycle (A) and heating cycle (B), based on a flow rate of 40 L s−1 and constant injection temperature of 80 °C in well BS-North (storage cycle) and 50 °C in well BS-South (heating cycle). Please note the change in temperature scaling between storage and heating cycles
