Joulia is a heat recovery technology that works very efficiently and reliably without moving parts or complex controls.
In other words, more efficiency and more comfort with lower costs for energy and the entire hot water infrastructure.
Instead of flushing the shower water into the sewerage system, the still warm water first flows through a double-walled heat exchanger, which extracts the heat from the waste water and thus warms the cold fresh water. This "preheating" means that much less hot water has to be added later at the mixer tap, saving over 50% energy, CO2 and money.
Joulia's shower channels can be combined with all types of hot water preparation and can be used in both new and renovated buildings!
The way we build our houses has changed massively in recent years. Originally, four walls were simply built and a roof was put on top of them, but in the 80s the home began to be better and better insulated. This the consumption of heating energy could be drastically reduced. At the same time, however, the demand for hot water remained constant and the energy consumption for it is therefore becoming more and more dominant in the energy budget.
