Enduce E1

Shower trays with 75 % energy recovery.

A new standard.

We see our floor drain as a new standard. There's a before and an after Enduce, as shower floor drains go from being beautifully designed holes in the ground to becoming energy and resource efficient. 

Our patented floor drain recovers up to 75% of the heat in the shower water - valuable energy that would otherwise go down the drain. In our solutions, economic and environmental sustainability go hand in hand. This gives our products a huge potential to both become market leaders and contribute to society's energy transition. 

In short, everyone wins with Enduce. A new standard for the industry.

questions and answers

Yes, the Enduce floor drain is based on an industrially proven technology, which we have adapted to modern bathrooms. The design is in line with industry and building standards and testing for floor drain function and waterproofing is done in the same way as with other products. The design principle has been to create something that is uncomplicated, robust and durable over time, making the lifespan of our product as long as the bathroom itself.

FAQ

The installation of the Enduce energy recovery floor drain leads to a significant reduction of energy consumption during the operational phase (EPD module B1).
Calcareous water does not have a problematic impact on the floor drain either on the gray water side (used shower water) or the tap water side. 
A hot water-based cleaning system heats, melts and flushes greasy deposits out of the heat recovery system's heat exchanger.
Series production and assembly take place mainly in Sweden. The product consists largely of recycled material. The brass is lead-free.
Enduce E1 meets the requirements of the Swedish National Board of Housing, Building and Planning. To date, the technology has been used over 15,000 times.
There are no regulations that prevent energy efficient technologies at the application level in showers.
