Surface water from rivers, lakes, or seas serves as an efficient energy source for heating and cooling via heat pumps. With increasing demand for sustainable energy solutions in light of climate regulations and urban development, this application provides an environmentally responsible option for municipalities, businesses, and residential areas.
Xylem provides complete solutions from site analysis, extraction systems, and treatment technology to turnkey delivery. Our projects in Germany—including the use of river water at a former industrial site in Bremen and sea water near the Baltic coast—demonstrate real-world feasibility, energy independence, and successful collaboration with local authorities and developers.
