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.

Patented innovation

Our solution has been developed over a long period of time and is patent protected both in Sweden and internationally. Five different patents protect the innovations that enable, streamline, improve and simplify the application of plate heat exchangers in grey water shower applications. This makes our solution world leading and positions us for a strong market position now and in the future.

Our future plans

There is a great need for energy efficiency globally. More and more incentives and regulations are coming into force, which strongly suggests solutions like Enduce E1. With an increased demand for sustainable solutions, we expect strong growth and have major plans for international expansion. Enduce is well positioned to meet this demand with scalable manufacturing, technology, unique know-how and several international patents.

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.

How you design the shower area and where you position the shower room ventilation are important factors that influence how energy efficient and comfortable the shower experience will be.
According to the Swedish National Board of Housing, Building and Planning's building regulations, the contribution of energy-saving technologies to improving energy performance may be included in the calculations based on the technology's demonstrated energy savings.
Enduce E1 reduces hot water consumption (the energy used to heat hot water), which is by far the biggest environmental and climate impact of showering.
The solution's operating principle is that the energy in the continuous flow of shower water is heat exchanged against the continuously incoming cold water.
The floor drain is also designed to be fully repairable. This means that all internal and moving components can be replaced if something breaks.   
The connection of the waterproofing to Enduce E1 is done via traditional clamping frame connections for either waterproofing foil for tiled floors, or for plastic carpet.
