How about more efficiency? delightful showering? a good conscience?

How about delightful showering, a good conscience and more eneryg efficiency?

Instead of letting valuable heat energy from shower water go to waste, the Joulia shower drain channel recovers this energy and provides a sustainable shower experience with the highest comfort level.

What customers love about Joulia:

Efficiency

Up to 60% energy savings.

Amortisation

Short payback thanks to reduced energy costs and smaller heating system.

Potable water

Compliant with the stringent regulations by KIWA, SVGW, WRAS & DVGW.

Simplicity

Quick installation and thorough cleaning.

Compactness

Same height as shower drain channels without heat recovery.

Durability

Dependable functionality with no moving parts.

Design

Sleek design, integrated invisibly into the shower drain channel.

Awarded

for the brilliant idea, the high effiency and easy handling.

Trap

Integrated directly into the heat recovery module (50mm).

Safety

Double separation between fresh and waste water.

Flow rate

High flow rate of 0.8l/s, also ideal for rain shower heads.

no electricity

No need for electricity or complex control systems.

Before
The cold and warm water is directly connected to the mixing valve. The used warm shower water regrettably flows into the sewerage system.

Thanks to the rerouting of the cold water –
 The Joulia-Inline shower drain channel is directly connected to the cold water pipes. Thanks to the integrated heat recovery, the heat of the used water…

– the heat energy comes back
preheats the fresh cold water. Thereby less warm water is needed in the mixing valve and a lot of CO2 and money can be saved.

Trap

Integrated directly into the heat recovery module (50mm).

Safety

Double separation between fresh and waste water.

Flow rate

High flow rate of 0.8l/s, also ideal for rain shower heads.

no electricity

No need for electricity or complex control systems.

Why waste water heat recovery

Thanks to ever stricter regulations on the building envelope and consequently thicker insulation, energy consumption for heating has been massively reduced over the past decades.

However, the energy requirement for hot water remains constant.

Due to the increased hygiene requirements and ever larger overhead showers, it can even be assumed that the energy consumption for hot water – and especially for showers – will increase even more

Nowadays a household needs the same amount of energy for hot water as for the entire space heating system.

Time to “plug” the last big hole in the insulation. Because it really makes no sense to produce a lot of hot water with valuable energy, which we dispose of after only two seconds of use.
