Joulia-Twinline
A simple yet ecological shower drain with heat recovery
01.
Identification
The impressively simple Joulia-Twinline technology proves that there is another way. By means of an ingenious heat exchanger module, the heat energy of the used shower water is reused to warm the incoming cold water mains. Thanks to this technology, 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. By this simple means, a 4-person household can save about 1900 kWh per year. Joulia-Twinline is particularly performant in places where many people shower, such as sport centres, gyms, hotels or clinics. A single Joulia- Twinline can generate about as much heat energy as a 15m2 photovoltaic array would produce in one year (1'900 kWh/a). Showering with a clear conscience is thus both ecological and delightful. The sophisticated technology is concealed under a simple stainless steel cover. Because the heat exchanger cover also serves as a trap, the total installation height is comparable to conventional shower drains and can also be used in renovations. The technology is practically instant and cleaning is simple thanks to the easily-removable cover.
