Enduce E1

Shower trays with 75 % energy recovery.

A new standard.

As an energy and HVAC consultant or designer, you play a crucial role in creating more energy-efficient and sustainable buildings. Our patented floor drain can be a central part of this equation. 

By recovering up to 75% of energy during showering, our solution offers significant energy and resource savings. Let's work together to create the future energy-efficient buildings.

Basis for design

We provide documentation for your design. Here on the website you will find dimensional drawings, instructions, BIM/CAD files, LCA calculations and EPD. As well as answers to many common questions about everything from flooring, acoustics, legionella, fire, etc.

Why Enduce E1?

The building sector accounts for a large share of energy use.

The housing and real estate sector is the sector that uses the most energy globally. In Sweden, the housing and services sector accounts for 39% of final energy use.

A significant part of the energy consumption is used for hot water production.

In a modern home, hot water consumption accounts for as much as 40% of the total energy consumption for heating.
Source: Based on Boverket's energy consumption for hot water production 25 kWh/m2 and an energy performance of the building 62 kWh/m2.

The shower is the major hot water consumer in households.

The shower combines the hottest water flow on average with by far the longest duration for each tap. Most often, heated water goes straight down the drain with no energy recovery.

Energy is by far the largest consumer of resources. not the water.
Resource consumption is mainly related to water heating rather than water consumption.

Energy recovery is most useful in the shower.
By placing the energy recovery unit in the shower, energy losses to the environment are minimized, providing the highest possible efficiency and amount of energy recovered.

By including Enduce in the design phase, energy calculations and operating budgets are at the right level from the start. The installation requires no major additional work as Enduce E1 in a practical sense replaces the traditional floor drain in the shower. 

Enduce is compatible with prefabricated bathroom modules.

Yes, Enduce floor drain is based on research-based and patented technology developed and verified over a long period of time.

The Enduce E1 is designed to operate to the standards of and has been tested in the same way as other similar products.

The floor drain is based on proven technology adapted to modern bathrooms and with solid know-how from research and industry. It is robust, with no wearing parts and clear installation instructions.

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).
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.
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 independent studies, recovering hot water energy at the application level directly in the shower area is the most efficient way to recover hot water energy that would otherwise be lost.
