This presentation was created and published by Ben Gravely of Holocene Technologies. It provides a short review of solar thermal history, come examples of successful solar thermal installations and an overview of the technology behind solar thermal.
There were various demonstrations of solar thermal in the 18th and 19th centuries, but the first modern solar collector was introduced in 1909. Today, solar thermal is used in residential homes, sometimes in conjunction with passive design, and for commercial institutions such as physical therapy centers, dental clinics and veterinary clinics, as the presentation states. The presentation ends with various diagrams of solar thermal water heating systems, noting that one of the newest designs is the non-pressurized drain back system.
