»Solar Thermal Systems« summarizes the theoretical and practical knowledge gained from over 20 years of research, implementation and operation of solar installations. This work provides answers to a variety of key questions by examining current solar installations, drawing upon past experiences and making proposals for future planning.

• How do system components and materials behave under continuous operation?
• Which components have proven themselves and how are they used properly?
• What are the causes of defects and how can they be avoided?
• How long is the service life of modern solar installations?
• What is the difference between the various solar collectors?
• What performance can be expected from solar installations?
• How are solar installations planned and structured correctly?

In addition to practical recommendations on implementation, the theoretical background is also clearly explained. This book is a valuable guide for all those who deal with solar technology and at the same time a reference for the daily work of planners and fitters. It will also prove a useful tool for training and education.
