Joulia-Inline

Showerdrain with heat recycling

Showerdrain reclaiming heat energy from used shower water by pre-warming the fresh water before it arrives at the mixer.

02

The showerdrain Joulia-Inline has to be connected to the fresh water. Thanks to the low building height it can be placed in every shower floor and will work wihtout any moving part or electricity. Other sanitary manufacturers can buy just the heat exchanger module.

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.
