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.
Up to 60% energy savings.
Short payback thanks to reduced energy costs and smaller heating system.
Compliant with the stringent regulations by KIWA, SVGW, WRAS & DVGW.
Quick installation and thorough cleaning.
Same height as shower drain channels without heat recovery.
Dependable functionality with no moving parts.
Sleek design, integrated invisibly into the shower drain channel.
for the brilliant idea, the high effiency and easy handling.
Integrated directly into the heat recovery module (50mm).
Double separation between fresh and waste water.
High flow rate of 0.8l/s, also ideal for rain shower heads.
No need for electricity or complex control systems.

Double separation between fresh and waste water.
High flow rate of 0.8l/s, also ideal for rain shower heads.
No need for electricity or complex control systems.
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.

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.
