RELaTED project will provide a framework for the integration of many renewable heat sources into a low temperature DH system. RELaTED started in October of 2017 as a new Horizon 2020 EU Research and Innovation project on low temperature district heating systems. It's objective is to provide a framework for the integration of many renewable heat sources into a low temperature DH system. So-called triple function substations are the core of the project, which allow for the incorporation of building integrated solar thermal systems and reversible heat pump units into the grid. The collaboration of companies as NIBE, METRO THERM, AVENTA SOLAR and Industrias IMAR will make it possible to develop and test all these three systems. The system will [...]
