A forward-looking construction project. StWZ Energie AG expanded the district heating network in the old town of Zofingen. By 2024, several house connections were to be connected to the existing network with the help of CASAFLEX DUO and PREMANT pipe systems. The first stage began in 2023, when the innovative pipe systems were successfully installed in the narrow streets of the historic surroundings.
Innovative solutions for historical challenges
Laying the district heating pipes in Zofingen's old town placed high demands on planning and execution due to the narrow streets and special conditions. To overcome these challenges, additional custom-made fittings were developed at the customer's request and installed directly on site.
The combination of rigid PREMANT and flexible CASAFLEX DUO pipes proved to be the ideal solution. The flexible CASAFLEX DUO system enabled the installation of tight bending radii and the avoidance of obstacles, while the PREMANT pipes ensured reliable heat transfer over long distances thanks to their stability and monitorability.
Professional expertise and efficiency combined
Thanks to the expertise of our fitters, the project was able to progress quickly despite the challenging conditions. The precise installation in the historic surroundings demonstrates the versatility and efficiency of the pipe systems used.
Sustainable and cost-efficient district heating solutions
The combination of flexibility and robustness of the CASAFLEX DUO and PREMANT systems not only enables a reliable heat supply, but also helps to reduce installation costs. With the successful implementation of the first stage in Zofingen, an important step has been taken towards a sustainable and future-proof energy supply.
