This guide offers home users a structured introduction to the fundamentals of solar thermal energy.
The book covers the essential steps from initial planning to ongoing operation. It begins with the basics of system variants, such as systems for domestic hot water preparation and combi systems for space heating support. The content details how to conduct a site analysis, including the optimal orientation and inclination of collectors, and aids in the selection of flat-plate or evacuated tube collectors. Furthermore, it addresses the correct dimensioning of buffer storage tanks and heat exchangers,as well as the legal and financial frameworks, including building permits and funding programs.
The installation and commissioning section provides practical instructions for mounting collectors and installing the solar storage tank. It explains the setup of the solar circuit, including the routing and insulation of pipes, the installation of the pump group, and the electrical connection of the control system. The process of flushing, filling, and venting the system is also described.
For operation and maintenance, the publication details how to monitor system pressure and temperatures and how to maintain the heat transfer fluid. A specific focus is placed on the annual inspection of the solar fluid, including the measurement using a solar thermal glycol concentration refractometer. It also covers the care of system components such as collectors and pumps.
Finally, the book explores advanced applications and system optimization. It presents concepts for achieving high solar coverage fractions, combining the system with low-temperature heating, and provides solutions for a solar heating for shed and outbuildings. Methods for performance enhancement, such as hydraulic balancing and adjusting control parameters, are also discussed.
