The losses in DH grids are a major obstacle to the utilisation of renewable heat sources and waste heat.

A significant reduction in the distribution heat losses is gained by the introduction of low-temperature DH.

The hypothesis of this project was that it is possible to develop and utilise technical solutions by which the total thermal, temperature and electrical losses in DH distribution systems can be further reduced. Modelling and simulation of the total distribution grid, including modelling of the individual components, were carried out. 

The model was able to identify and eliminate potential component sub-optimisation and point out other potential critical focus areas in the DH grid. The project included a review of innovative designs and concepts of distribution pipes and other components.
