Waste Water Heat Recovery (WWHR) is a technology that captures and reuses the thermal energy present in wastewater from various sources, primarily showers, baths, and sometimes other appliances like dishwashers and washing machines.
Instead of this heat going down the drain and being lost, a WWHR system extracts it to preheat the incoming cold water supply, reducing the energy needed to heat water to the desired temperature.
Waste water heat recovery is a practical and increasingly popular technology for improving energy efficiency and reducing the environmental impact associated with hot water usage in both residential and commercial buildings.
By capturing and reusing heat that would otherwise be wasted, it offers significant energy and cost savings.
