Joulia - taking a shower

Instead of flushing the valuable heat of the shower water down the drain, Joulia’s shower channel recovers this energy and easily ensures sustainable showering enjoyment with full comfort.

The reason was that the new technological developments of the last few years could no longer be could no longer be reflected. In addition, the energy laws adopted by the electorate were to be integrated. Generally speaking, it makes sense to review the building standards every every 5 years makes sense. Building takes time, so rapid changes cannot be implemented immediately. We have to find a balance between reliability, planning security and the latest technologies for everyone involved. That is why we have only optimised the Minergie standards selectively since then – and will continue to proceed very cautiously.


Providing a shower concept that is water-saving and cost-effective, yet can be used with comfort – for heat recovery
