Warmte Congrestival is dedicated to accelerating the shift toward modern, sustainable, and green heating networks. While the speakers emphasised the importance of innovation, they also underlined a major challenge: the lack of strong and consistent European policy frameworks to support and speed up the transition.
This gap means that industry frontrunners must take initiative, paving the way for others to follow. At Thermaflex, we are proud to contribute to this change. With advanced piping solutions such as Flexalen® 600, we actively support the development of future-proof district heating systems.
Flexalen® at the Warmte Congrestival 2025
On 20 November, Thermaflex took part in the Warmte Congrestival, organised by Stichting Warmtenetwerk. Our technical specialists, Brian Goedhart and Jelmar van Beek, proudly represented the company at this leading industry event. The Congrestival was held in Nijkerk, the Netherlands, and brought together over 350 professionals from the heating and energy sector.
Flexalen® 600: Proven Sustainable Excellence
Our Flexalen® 600 pre-insulated pipes received significant attention on the exhibition floor, where participants could explore the system up close. Thanks to its exceptional flexibility, durability, and high chemical resistance, Flexalen® 600 is ideally suited for demanding applications, including harsh geothermal water used in district heating networks.
In addition, Flexalen® 600 is Cradle to Cradle Certified®, highlighting its proven sustainability and contribution to circular energy infrastructure.
