Solar Combisystem

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A solar combisystem is a solar heating system that provides renewable heat, both space heating and cooling and hot water from a common array of solar thermal collectors, normally linked to an auxiliary non-solar heat source. Solar combisystems may range in size from those installed in individual properties to those serving several in a block heating scheme. Those serving larger groups of properties district heating tend to be called central solar heating schemes. A large number of different types of solar combisystems are produced - over 20 were identified in the first international survey, conducted as part of IEA Task 14 in 1997. The systems on the market in a particular country may be more restricted, however, as different systems have tended to evolve in different countries. Prior to the 1990s such systems tended to be custom-built for each property. Since then commercialised packages have developed and are now generally used.
