Summary
The Swedish city of Lund is home to the world’s largest low-temperature district heating system, a shining example of an optimised fossil-free network that not only reduces cost but also minimises environmental impact.
Enlit on the Road visited the Brunnshög area to learn how Swedish utility Kraftringen, in collaboration with the Municipality of Lund, has created a model for the efficient recovery and distribution of waste heat, blending technical innovation and urban planning into a future-proof energy system.
According to Martin Gierow, Product Manager at Kraftringen, the system’s uniqueness lies in its low operating temperature—65°C compared to the typical 100°C used in conventional systems.
This lower temperature results in reduced heat loss in distribution, and crucially, allows the use of plastic pipes instead of steel, making installation more efficient and less labour-intensive. “We don’t have to weld every 12 metres,” Gierow notes, which significantly cuts construction time and cost.
