A district heating network is a system of pipes that transports hot water from a central heating plant to multiple buildings in an area. The water in the network is used to transfer heat energy—not consumed—and then circulates back to be reheated.

In each building, the district heating substation receives the hot water via heat exchangers, which transfer the energy to the building’s heating system and domestic hot water without mixing the network water with the internal system. Together, the district heating network and the substation form an efficient, reliable, and climate-smart system for heating homes and premises with minimal environmental impact.
