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 and answers to many common questions about everything from flooring, acoustics, legionella, fire etc. (see our FAQ). 

If you are looking for CAD files, LCA calculations or other data or documentation, it is no more than an email or phone call away. We welcome your questions and requests.

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.

questions and answers

Enduce gives immediate effect and is a long-term solution, which continues to pay off over time. In addition to money and new business opportunities, we save on the earth's and society's resources.

In residential buildings, tap water is one of the biggest energy wasters - the heat goes straight down the drain. With Enduce, up to 75% is recovered, which greatly reduces operating costs. For an apartment building, this can mean a reduction of over 10% for the entire property.

The large energy savings in the projects contribute to opportunities for green loans, procurement benefits and meeting industry regulations and environmental directives. Wise environmental choices also strengthen your employer brand and make the property more attractive to the end customer.

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.

Enduce E1 is designed to work according to the standards found in and is also 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

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.
