Abstract
In many countries, district heating (DH) has a key role in the national strategic energy planning. However, tighter legislation on new and future buildings requires much less heating demand which subsequently causes relative high network heat loss. This will make current DH system uneconomical comparing with other local heat generation units. The design and operation of DH systems therefore needs to be re-examined, part of the solution being low operational temperature. The 3-years IEA DHC Annex X project ‘Towards 4th Generation District Heating: Experience and Potential of Low-Temperature District Heating (LTDH)’ aims to document experiences gained in mature DH countries with low temperature systems serving highly energyefficient new buildings and existing buildings. The potential to supply DHW at temperature close to 50oC without the risk of Legionella was investigated. Information on optimal DH network design and decentralized heating supply has been reported. The technical and economic feasibility to supply LTDH in different countries/regions was reported.
