In modern buildings, energy is being used increasingly efficiently. Photovoltaic systems, heat pumps, and geothermal probes are now well-established components of sustainable energy concepts and contribute significantly to reducing energy consumption and CO₂ emissions. However, one energy source often remains unused: the heat contained in domestic wastewater.
Every day, activities such as showering, washing, and cooking generate warm wastewater that leaves the building through the sewer system. This wastewater contains considerable thermal potential that can be utilized for building services engineering.
Wastewater heat recovery makes it possible to return this energy to the building’s energy cycle.
