Showering, making coffee, washing clothes: we use liters of water every day. And this is often heated at great expense. With electricity or gas. Then it goes into the sewer system and is... gone! Kind of a shame, isn't it? Can't the water that has been heated at great expense be used in some other way? Felix Drechsel (26) asked himself this question. He and his team have developed a system that collects the wastewater from individual apartments and converts it into heat, which can then be used to heat new water in the individual rental apartments. Felix and his hot water solution not only save the residents money, but also drive the energy transition forward. But the device is still difficult to install. Wastewater from the toilet is not suitable for generating heat. So Felix and his team are working on programming an AI that solves the problem. You can see the tricks and gimmicks that make it work in the video. #simplybrilliant #inventions #wastewater ???? In the video: FELIX DRECHSEL, studied construction management. Since 2020 he has had his own startup in which he implements his invention: the wastewater heat exchanger and the wastewater switch. BEN SCHÄFER, is an engineer and employee of Felix Drechsel. He has been working in the team since 2021 and has helped develop all of the systems. JENS FISCHER, is head of the planning office that installed the first prototype of the wastewater heat exchanger in Stadtroda. SUSANNE LIPPMANN, she is the technical director of a housing association in Jena. In her department it was decided to install the plate heat exchanger for large residential complexes in some houses. MARTIN PERSCH, he is an energy consultant from consumer protection in Erfurt and is checking how the invention works. ????
