The combination of a revincus heat recovery system with a GreenLife greywater recycling system is one of the most efficient solutions for modern water management and energy-efficient building optimisation. While the GreenLife system specialises in treating lightly contaminated waste water from showers and washbasins and providing it as valuable service water for toilet flushing or garden irrigation, revincus closes the thermal gap in this cycle.
The key advantage lies in the synergistic use of energy: shower water usually leaves the building at a temperature of over 30 °C. Without heat recovery, this valuable thermal energy would flow unused into the sewage system. The revincus system extracts heat from the grey water before it is purified in the GreenLife process and uses it to preheat the cold drinking water supply. This means that the primary heating system – such as a heat pump or solar thermal system – has to work much less hard to bring the water back up to the desired comfortable temperature.
This interaction results in double resource efficiency. Users not only benefit from a reduction in drinking water consumption of up to 50%, but also massively reduce the energy costs for hot water production. This leads to significant CO₂ savings and increases the self-sufficiency of the building. Particularly in larger residential properties or hotels, this combination leads to a significantly faster amortisation of the system costs, as operating costs are reduced on two fronts simultaneously.
In addition, heat recovery optimises the biological processes within the recycling system. As the water is cooled in a controlled manner before storage, system stability is increased. Overall, revincus and GreenLife transform a building from a passive consumer into an active recycling system that combines ecological responsibility with economic foresight and easily meets the highest energy standards such as GEG or KfW efficiency house requirements.
