Efficient district heating network operation starts in the basement: what modern building connection stations mean for network operators and connection holders

Building connection stations have a direct impact on the efficiency of a district heating network. High return temperatures, poorly adjusted control systems or outdated heat exchangers drive up network losses and make it difficult to reduce system temperatures, which is necessary for efficient operation and the use of renewable heat sources.

The presentation outlines the requirements that a modern building connection station must actually meet – from control technology to sizing – and the resulting implications for network operation. This provides network operators with guidance for their modernisation strategy and funding planning, whilst giving connection holders an understanding of the requirements and investments they will actually face. Economic and legal issues, such as funding opportunities or the adjustment of connection capacities, are also addressed.

The topic is illustrated using a real-world portfolio of 45 domestic connection stations, as well as through a practical perspective: a managing director who is familiar with both the network operator’s and the property owner’s sides of the business shares his views on the upcoming modernisation.
