Identification

Reclaim valuable heat energy from used shower water by pre-warming the fresh water before it arrives at the mixer. Up to 42% of thermal energy can be saved by each warm shower. The showerdrain Joulia-Inline has to be connected to the freshwater. By means of a heat exchanger module, the heat energy of the used shower water is reused to warm the incoming cold water mains. In this way the cold water arrives at the mixing valve up to 15°C warmer than before (from 10°C up to 25°C). Therefore, substantially less hot water is needed. By this means, a 4-person household can save about 1000 kWh per year. Joulia-Inline is sold with either 3 or 5 heat exchanger tubes, which you can select depending on whether maximum efficiency or minimal installation height is more important.

  • Save as much energy as 8 m2 of solar panels would have to produce and this whilst showering
  • Certified for connection to drinking water in many European countries
  • The drain doesn't emit any CO2 in the atmosphere, doesn't use any electric energy, just works by water flow
  • Closing the last gap in the building envelop with Joulia-Inline shower drain channels with integrated heat exchangers
