Effective measure against global warming:
Taking a warm shower with Joulia.
How about more efficiency? delightful showering? a good conscience?
How about delightful showering, a good conscience and more eneryg efficiency?
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.
Efficiency
Up to 60% energy savings.
Amortisation
Short payback thanks to reduced energy costs and smaller heating system.
Potable water
Compliant with the stringent regulations by KIWA, SVGW, WRAS & DVGW.
Simplicity
Quick installation and thorough cleaning.
Compactness
Same height as shower drain channels without heat recovery.
Durability
Dependable functionality with no moving parts.
Design
Sleek design, integrated invisibly into the shower drain channel.
Awarded
for the brilliant idea, the high effiency and easy handling.
Trap
Integrated directly into the heat recovery module (50mm).
Safety
Double separation between fresh and waste water.
Flow rate
High flow rate of 0.8l/s, also ideal for rain shower heads.
no electricity
No need for electricity or complex control systems.
Before
The cold and warm water is directly connected to the mixing valve. The used warm shower water regrettably flows into the sewerage system.

preheats the fresh cold water. Thereby less warm water is needed in the mixing valve and a lot of CO2 and money can be saved.

Joulia-Inline
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.

The thermal imaging camera makes it clear: After the heat exchanger, the used shower water now flows cold into the sewer system.
Wenn ich selber einmal Bauherr bin, werde ich als Warm- und Langduscher eine Joulia-Duschrinne einbauen lassen.
Joulia ist ein hervorragendes Beispiel für "Cleantech made in Switzerland".
Joulia-Inline ist Designprodukt und technische Innovation in Einem.
Joulia hilft Energie zu sparen an einem Ort, an dem das Potential für viele nicht sichtbar ist.
Joulia steht für eine unmittelbar einleuchtende Idee, bei der man sich im Nachhinein nur wundern könne, dass zuvor noch niemand darauf gekommen sei.
