Our guidebook contains aggregated information about the main economic drivers for low-temperature district heating. It shows how to obtain lower temperatures in heating systems inside existing and new buildings, as well as in existing and new heat distribution networks.<\/p>\n\n\n\n

Toolbox to obtain low temperatures<\/h2>\n\n\n\n

Given customers have a substantial influence on a district heating system\u2019s return temperature, a simple method is described for identifying crucial customers from an operator\u2019s point of view.<\/p>\n\n\n\n

In chapter 4, we go deeper into the following measures to obtain low temperatures:<\/p>\n\n\n\n

    \n
  1. Tracking malfunctioning substations<\/li>\n\n\n\n
  2. Identification of unintentional circulation flows<\/li>\n\n\n\n
  3. Addressing bottlenecks in network sections<\/li>\n\n\n\n
  4. Successful cases of reduced temperatures<\/li>\n\n\n\n
  5. Sub-networks<\/li>\n\n\n\n
  6. Cascading solutions<\/li>\n\n\n\n
  7. Heat pumps to address subsection demands<\/li>\n\n\n\n
  8. Increased decentralized supply<\/li>\n\n\n\n
  9. Digitalization opportunities<\/li>\n\n\n\n
  10. Design criteria for new systems<\/li>\n\n\n\n
  11. New innovative supply and distribution concepts<\/li>\n<\/ol>\n\n\n\n

    About the book<\/h2>\n\n\n\n

    This guidebook was written between 2018 and 2021 by seventeen authors that used approximately 15 000 hours of work within the IEA DHC TS2 annex. The content is based on more than 250 literature references and 165 inspiration initiatives to obtain lower temperatures in buildings and heat distribution networks. The author group wrote 40 internal documents about early implementations of low-temperature district heating. Book info by the publisher<\/a>
