1. Durability of District Heating Pipes
Abstract : This thesis is focused on mechanical loads and moisture related problems with a potential to critically harm the functionality of pre-insulated district heating pipes and pipe joints. Directly buried pipeline bends are investigated with respect to limiting deformations from a thermally induced lateral displacement. READ MORE

2. Low-temperature District Heating : Various Aspects of Fourth-generation Systems
Abstract : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

3. Modelling District Heating Network Costs
Abstract : The solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the European continent, it is still mostly supplied by fossil fuels.

4. Small District Heating Systems
Abstract : The objective of this work is to identify, from an economical point of view, the optimal system design and operation strategy for the district heating of a small residential area. The applied methodology is an overall approach on the heat distribution system, the house connection and the space heating system in the building, i.e. READ MORE

5. Solar District Heating for Low Energy Residential Areas : A Technical Analysis of Heat Distribution Concepts for a Solar Assisted District Heating System
Abstract : The integration of a solar thermal system into a district heating network can be a cost-effective solution, especially for new low-energy residential areas. Because of this, many new small solar district heating systems are built at the same time as the buildings, allowing for a more holistic approach to the design and construction. READ MORE
