Our Enduce E1 energy recovery shower floor drain is simple, efficient and a real resource saver. The heat from used shower water is passed through a heat exchanger that preheats the cold water for the shower mixer, reducing energy and hot water consumption by up to three quarters.

Uniquely, the Enduce E1 solution is passive (no electrical connections, pumps or replacement filters) combined with world-leading efficiency, making it incredibly cost-effective and robust. An integrated cleaning system prevents clogging of the heat exchanger, which has previously been a barrier to high-efficiency energy recovery from shower water.

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.

Eurostat, Energy consumption in EU households, 2020.

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.

FAQ

The design of the shower area and the location of the ventilation system play a major role in shower comfort, bathroom climate and, not least, energy efficiency.  
According to Boverket, the contribution of energy-saving technologies to improving energy performance may be included in the calculations based on the demonstrated energy savings of the technology.
Enduce does not reduce water consumption overall, but hot water consumption does. The resource saving lies mainly in the energy and not in the water.
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.
Enduce's high demands on long service life and full repairability form an important part of the product's good economic profitability as well as environmental and climate sustainability. 
The connection of the waterproofing layer to the floor well takes place either via a traditional clamp frame connection for waterproofing foil or for plastic mat. 

Testa Enduce E1

Our demos allow real estate companies to test and evaluate the Enduce E1 in existing stock without breaking the waterproofing. The shower trays are easy to install in existing homes and can be fitted with loggers to measure savings on an ongoing basis.

Enduce E1 is designed to work according to the standards in place and is also tested in the same way as other similar products. The floor drain is based on proven technology adapted to modern bathrooms. Genuine know-how from research and industry is behind our innovation and patents. The product is robust, with no wearing parts and clear installation instructions. 

Enduce has an immediate impact and is a long-term solution that continues to pay off over time. 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 10-15% for the entire property. The large energy savings in the projects contribute to opportunities for green loans, procurement benefits and meeting the industry's environmental directives.
