Aufgrund der relativ einfachen Upgrade-Umwandlung von Wasserversorgungs-Netzen zu Kombi-Wasser/Wärme-Rohrleitungs-Netzen ist davon auszugehen, dass die Erfindung einen ökologischen und ökonomischen Beitrag leisten kann, um den weltweiten Bedarf an klimaneutraler regenerativer Wärme-Energie zu decken.
