District heating systems will be progressively more competitive if their global efficiency is increased. One of the main actions to implement in order to reach that increased efficiency is decreasing the operating temperature. In the literature, “the 4th generation district heating systems” are traditionally identified as the ones characterized by a limited operating temperature and, as a consequence, by high efficiency during operation.
Bearing in mind the reduction of operating temperatures, the pipelines with plastic service pipes will be used more predominantly in the manufacture of district heating systems. ECOPEX® flexible preinsulated pipes represent the ideal solution to realise small and medium district heating networks characterized by limited operating temperatures, for industrial, commercial and residential applications.
