Instead of letting valuable heat energy from shower water go to waste, the Joulia shower drain channel recovers this energy and provides a sustainable shower experience with the highest comfort level.
Thanks to the rerouting of the cold water –
The Joulia-Inline shower drain channel is directly connected to the cold water pipes. Thanks to the integrated heat recovery, the heat of the used water…
Thanks to ever stricter regulations on the building envelope and consequently thicker insulation, energy consumption for heating has been massively reduced over the past decades.
However, the energy requirement for hot water remains constant.
Due to the increased hygiene requirements and ever larger overhead showers, it can even be assumed that the energy consumption for hot water – and especially for showers – will increase even more
Nowadays a household needs the same amount of energy for hot water as for the entire space heating system.
Time to “plug” the last big hole in the insulation. Because it really makes no sense to produce a lot of hot water with valuable energy, which we dispose of after only two seconds of use.

NOVEMBER 25, 2021
On 25 November 2021, the first door-opener event took place at Joulia in Biel. Together with energie-cluster.ch and Swissframe AG, we dedicated an evening to the topic of heat recovery. Speakers from the Lucerne University of Applied Sciences and Arts, s3 GmbH, Franz Kaldewei GmbH + Co. KG and ACO AG gave presentations and were there afterwards at the Networking & Apéro to answer questions and present their latest products.
