Wastewater is an energy source that is available constantly and in large volumes. Every day, millions of households, plus commercial and industrial concerns, pour vast quantities of heating energy down the drain in the form of wastewater. This energy can be recovered using wastewater heat exchangers and used. This makes economic and ecological sense and can boost climate protection and energy transition considerably.
Buildings can be both heated and cooled using energy from wastewater. This form of energy is already competitive. Heat from wastewater is CO2-free and represents a major opportunity for energy transition in the heating market. In Germany alone, up to 14 % of the demand for heat in buildings can be met with energy from wastewater. Wastewater is an energy source that has major potential in urban areas in particular. Because wherever there are lots of people, there is also a great deal of wastewater and a high demand for energy. Supply and demand fit perfectly.
