Heating water with the sun is almost as old as humankind itself, and it is done all over the world. Yet there are strangely few resources on the topic in North America. Solar Water Heating fills this gap. It reviews the history of solar water and space heating systems from prehistory to the present, then presents the basics of solar water heating, including an introduction to modern solar energy systems, energy conservation and energy economics. Drawing on the author’s experience as an installer of these systems, the book goes on to cover: Types of solar collectors, solar water and space heating systems and solar pool heating systems, including their advantages and disadvantages System components, their installation, operation, and maintenance System sizing and siting Choosing the appropriate system. Since people often get turned off by the up-front cost, the book focuses especially on the financial aspects of solar water or space heating systems, clearly showing that such systems can save significant costs in the long run. Well-illustrated, the book is designed for a wide readership from the curious to the student or professional. Bob Ramlow is the solar thermal consultant for the Wisconsin Focus on Energy Program.
