Joulia SA


Joulia SA has been founded in 2010 to commercialize an innovation originally developed at the innovation house Creaholic. The Joulia SA operations team is an interesting mix of different professions and talents and cut no corners in turning a bold idea into a product with great market potential. The Joulia shower drain with heat recovery offers all the comfort and soothes your guilty conscience. With Joulia, heat recovery is very attractive. This scalable heat recovery module is invisibly integrated into a slim channel in the shower floor, and efficiently recovers heat energy from the warm shower water as it goes down the drain. In this way it provides more comfort while using less energy. And in order to recover as much energy as possible, Joulia has already found 3 well known sanitary manufacturers like KALDEWEI, DURAVIT and ACO, that will integrate the heat exchanger module into their own range of products. So it will soon be possible to enjoy showering in hotels, SPAs and gyms also in shower trays and custom made row shower drain channels, recovering up to 50% of the otherwise lost heat.
