Freilager
Zurich
The City of Zurich implemented 47 Joulia-Inline shower drains in its brand new school facility “Freilager” in 2022. Some of these drains are made of special stainless steel in order to resist chlorine air in the swimming area. The facility is built under the Minergie-P-Eco label with low energy consumption. A local district heating using waste heat from a data center and heat pumps supply the facility. The showers are not only used by the school, but are as well open to the public in the evening.
Recovered up to 42% of heat that would have otherwise been lost from showers, significantly improving energy efficiency and enhancing sustainability performance, contributing positively to the company's environmental impact goals.
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.
