Abstract: The application of renewable heat supply technologies underlies various constraints. To overcome these limitations to their application in this research, an interconnection of different heat sources in the so-called Heat-Dispatch-Centre is derived from the main characteristics of renewable heat supply technologies. A season-dependent operation state of generation and storage units allows low-emission and efficient heat supply. In addition, alternative connection possibilities are discussed and a visualization method for an analysis of heat generation units connected in series is introduced. For an exemplary network an overall primary energy factor of 0.09 and a specific CO2 emission factor of 27 gCO2/kWh is reached, with costs of overall heat generation at 11–12 €ct/kWh. In contrast to this, a parallel connection of the heat sources reduces overall efficiency, increases the costs to 13 €ct/kWh and increases the CO2-emissions in the overall energy supply system by decreasing renewable electricity infeed into the grid.
