#209 Flusswärmepumpen und Wärmenetze für die Wärmewende ✦ Podcast Klima und Kohle

In this episode, we examine how the heating sector can be decarbonized when natural gas is phased out. This is prompted by an inquiry from SWR (Southwest German Broadcasting) regarding the town of Ladenburg on the Neckar River, whose gas supplier will cease deliveries of natural gas in 2035. I explain how heat pumps work, compare air and water sources, and discuss the role of river heat pumps in conjunction with district heating networks. Using practical examples from Mannheim and Esbjerg, Denmark, I demonstrate what is technically and economically feasible and highlight the obstacles related to connection rates, electricity prices, and subsidies. These examples illustrate the technical and economic possibilities. ✦ Chapter ✦ 00:00:00 Introduction 00:01:44 Example: Ladenburg 00:03:17 Heating demand in Germany 00:04:38 Old buildings, insulation, and U-value 00:12:18 Heat pumps as a solution 00:13:07 How a heat pump works 00:20:11 Water instead of air as a heat source 00:23:18 Mannheim and Denmark 00:28:30 Hurdles and connection rates 00:33:42 Electricity prices and subsidies 00:38:46 Conclusion Listen to the podcast episode on 🎧 ✦ Podigee: https://hteheesen.podigee.io ✦ Spotify: https://open.spotify.com/show/5WvLZvT... ✦ Apple Podcasts: https://podcasts.apple.com/de/podcast... ✦ Amazon Music: https://music.amazon.de/podcasts/923b...
