Linear Drain

Wonderfully simple and brilliantly designed

View Downloads

The Showersave Linear Drain sits perfectly in our portfolio of energy recovery systems. It is wonderfully simple and brilliantly designed while working in a similar way to our existing, proven vertical systems. Instead of flushing valuable energy straight down the drain, the Showersave Linear Drain helps plug the last gaping hole in an otherwise perfectly insulated home.



The Showersave Linear Drain is suitable for Apartments, bungalows, Retrofit in bathroom refurbishments and wet rooms.

“The technical implementation seems very professional. Linear Drain should be in every home!” (Swiss Design Awards – Judging Panel)

Maintenance & Cleaning

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 Linear Drain 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.
