Joulia always fits. Whether it's a new build or renovation, we support customers in rental apartments and single-family homes as well as in hotels, commercial properties, and fitness and spa facilities.
Experience that pays off: In apartments and single-family homes, Joulia saves CHF 100–200 in ancillary costs annually. This means that the investment usually pays for itself in less than 5 years. Another plus point: thanks to efficient heat recovery, all building services—from hot water storage to heat generation—can be scaled down, which saves additional costs.
Yes, cleaning is just as easy—if not easier—than with a conventional shower channel. The hair trap is easy to clean and the heat exchanger can be accessed at any time in just a few simple steps. This makes Joulia the most maintenance-friendly solution on the entire market.
Installing a shower channel is very simple. The plumber only needs to connect the cold water supply to the channel first, before the preheated water goes to the shower mixer. If you have any questions, our team is always available to help.
Joulia fits into any project. The gutters are ideal for new construction and renovation. We place great importance on architectural freedom: our technology adapts flexibly to design requirements and structural conditions.
Regardless of whether you already know which system is right for you, we will support you with a customized quote.
