District steam and pump hot water (PHW) from the energy supplier Waste and Recycling Zurich (ERZ) are available for heat supply.

Individual buildings are already heated using PHW; The provision of domestic hot water (TWW) is also partially covered via the PHW network. The PHW network has several heat transfer stations, each equipped with several heat exchangers. The total thermal output of the network is over 30 MW.
