Saves up to 60% of the energy per shower!
Waste Water Heat Recovery for Showers (WWHRS) is a technology increasingly implemented in new buildings and social housing. It is a straightforward system that captures heat energy from waste shower water using a heat exchanger. This recovered energy is then utilized within the shower system, resulting in cost savings, energy conservation, and reduced carbon emissions.
How Waste Water Heat Recovery Works for Showers
Approximately 85-90% of the heat energy from showers is lost down the drain. Waste Water Heat Recovery for Showers (WWHRS) captures this heat from the shower's waste water and transfers it to the cold water supply of the shower and/or the property's water heater. This process reduces the need for hot water during showers, leading to energy savings and lower household costs.
Vertical WWHRS
Wastewater from the shower passes through a copper heat exchanger, while cold mains water circulates around it.
Horizontal WWHRS
Waste water from showers flows over a copper heat exchanger, while cold mains water circulates through the exchanger.
The installation method for System A is illustrated above. It works by sending preheated water to both the water heater and the cold side of the shower, ensuring maximum efficiency and significant savings. In contrast, System B directs the preheated water solely to the shower. This approach is ideal for easy retrofits, upgrades, and situations where a second system is necessary within a property.
