Shower drain warms water while conserving energy

The Joulia shower drain recovers heat from hot water, saving 60 per cent of the energy needed to warm water for future bathing

Spotted: Switzerland-based company, Joulia, has created a shower drain that preheats cold water using heat recovered from previous showers. The shower drain offers an efficient and accessible way to reduce energy consumption.

With traditional systems, heated water drains into the sewer system after a shower. 

The Joulia system, however, is connected directly to the cold water pipes and uses heat recovery technology to capture the warmth from used water to preheat fresh cold water. That means less hot water is needed to reach a comfortable temperature for future showers, reducing energy consumption. 

Springwise has spotted other innovations that reduce household water waste, including a showerhead that uses less water.
