The Joulia Drain works in the same way as our Vertical System . With the Showersave “Joulia” drain, heat recovery is straight forward. 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.
All parts of the heat exchanger can easily be cleaned, serviced or even replaced. For cleaning you can simply remove the green trap cover to access the heat recovery module. Any residues can by easily removed by using a brush and mild detergent.
All components of the Joulia-inline technology were developed according to the test criteria of KIWA as well as of SVGW, and are registered there for certification. The integrated trap meets the requirements of EN1253.
Simple to install in single storey dwellings, especially apartments.
Cleverly designed to ensure ease of cleaning and maintenance
Compact design – same size as standard drains without heat exchangers
Integrated, designed and approved trap – no need for external trap
>35% efficiency @ 11 l/min
Saves as much energy per year in a 4 person household as 8m² of Photovoltaics would create
The QB-1 range,a tubular heat exchanger suitable for first-floor showers, comes in three versions. The QB1-21 (standard), QB1-21C & QB1-21D
C is for the Cyclone inlet option, which adds 1.2% efficiency at a 11 litres/min flow rate.
D is for the Double QB1 model for higher flow rate installations.
