Tiivistelmä
The objective of this thesis was to present available leak detection methods in the context of Finland's district heating networks, emphasizing their impact on operational reliability, cost efficiency, and customer satisfaction.
The first part of this thesis provides an overview of district heating systems in Finland, emphasizing the critical importance of addressing pipeline leaks. The theoretical framework then explores various leak detection methods and their underlying technologies, including two types of alarm cabling systems one based on resistance measurement and the other on time-domain reflectometry (TDR) pulse technology along with thermal imaging and external notification methods. Each method’s technical principles, benefits, and limitations are discussed in detail.
The research methodology centers on qualitative interviews with industry experts to assess the operational effectiveness and user experiences with these technologies. Additionally, the thesis includes a case study on the implementation of the Vexve iSense system in a district heating facility, offering practical insights into its utility and environmental impact.
The findings demonstrate that advanced leak detection systems significantly enhance the efficiency and reliability of district heating operations. These technologies not only reduce operational disruptions and maintenance costs but also improve customer satisfaction through increased service reliability.
In conclusion, this thesis underscores the critical role of advanced leak detection technologies in supporting sustainable and efficient district heating. The research offers valuable guidance for district heating providers in making informed decisions about technology selection and infrastructure investment, ultimately contributing to greater resilience and customer satisfaction within Finland’s evolving energy market.
