8. Fault handling processes in district heating customer installations : Current and future solutions
Abstract : When trying to integrate more fossil-free heat sources such as renewable energy and heatrecycled from other processes into the current district heating systems, problems occur due tothe high temperature levels in the systems. There are many reasons to why the temperaturelevels are high, but one frequently occurring issue is that the return temperatures of thecustomer installations are undesirably high due to faults in the substations or internal heatingsystems of the installations.

9. Spot the difference! : On the way towards automated fault handling in district heating buildings
Abstract : This thesis focuses on how district heating utilities may work with fault handling in customer installations as a tool to reduce their return temperature levels. Reduced return temperatures would make it possible to improve the efficiency of the district heating systems and decrease their environmental impact. READ MORE
