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.

It's that simple

Before
The cold and warm water is directly connected to the mixing valve. The used warm shower water regrettably flows into the sewerage system.

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…

– the heat energy comes back
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.

What customers love about Joulia:

Why waste water heat recovery

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.

JULI 1, 2020

10 years of Joulia

Exactly 10 years ago to the day we founded Joulia SA together with the innovation house Creaholic and the FFF – Friends, Fools and Families.

What started with a bold idea has now been installed in thousands of bathrooms and recovers valuable energy every day.

Together with our loyal shareholders, this 1st Jouli was celebrated on a small scale. We were particularly pleased that a delegation from WIELAND joined the shareholders in celebrating the next stage of Joulia’s expansion. We are looking forward to an inspiring collaboration and to making the shower water heat recovery system even more popular.

And of course Mr. James Prescott Joule was not to be missed among the guests…
