„Die Wärme des Sommers in den Winter retten“ - Eine Studie am Karlsruher Institut für Technologie zeigt, wo in Deutschland das Grundwasser als Wärmespeicher genutzt werden kann. - Campus-Report am 06.12.2022

In these cold December days in the middle of an energy crisis, with a maximum room temperature of 19 degrees, we wistfully remember the past summer. If only the heat that made us sweat in August could somehow be saved and used for heating in December! In fact, you can do that if you use the groundwater as a heat storage medium. Conversely, the icy temperatures of winter can be used for cooling during the heat waves of summer. An enormous savings potential when you know that in Germany a good third of all energy is required for heating and cooling buildings. A research project at the Karlsruhe Institute of Technology shows where the best locations for storing summer heat in groundwater are.
