Enduce E1
Maximum energy savings. Minimum effort.
The hidden energy bill in buildings
In modern buildings, hot water heating accounts for up to 40 % of total energy consumption - a share that has increased as buildings have become more energy efficient. At the same time, huge amounts of thermal energy are washed down the drain without being recovered.
The Enduce E1 recovers a large part of the heat in the wastewater, creating direct energy savings, reducing power demand and improving the energy performance of the building - without affecting comfort or operation.
The real estate sector accounts for a significant share of energy use.
The construction and real estate sector accounts for 39 % of Sweden's total energy consumption - equivalent to 144 TWh per year.

A large part of the energy is used for hot water production.
In newly built homes, up to 40 % of total energy use goes to hot water.
Source: Based on the Swedish National Board of Housing, Building and Planning's energy consumption for hot water production 25 kWh/m2 and an energy performance of the building 62 kWh/m2.
The shower is the largest consumer of hot water in households.
The shower combines high water flow with a long usage time, making it the single biggest energy consumer in households.

Local energy recovery in the shower is the most efficient solution.
Locating heat recovery directly in the shower minimizes energy losses and maximizes recovery rates. Studies show that heat recovery in the shower can provide up to 80 % higher efficiency than centralized solutions.
