A showerdrain that reclaims up to 60% heat energy from used shower water by pre-warming the fresh cold water
Reclaim valuable heat energy from used shower water by pre-warming the fresh water before it arrives at the mixer. The shower drain Joulia 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 20°C warmer than before (from 10°C up to 30°C). Therefore, substantially less hot water is needed. Joulia-Inline is sold with either 3 or 5 heat exchanger tubes, and Joulia-Twinline with 6 or 10 which you can select depending on whether maximum efficiency or minimal installation height is more important.
Recovery rate of up to 42% of otherwise lost heat from the showers
