So How Does a Solar Hot Water System Work?
Solar water heating is a very simple system. Special solar panels, called solar collectors, are installed on a roof or in the garden. These collectors collect heat from the sun and use it to warm up water. This water is stored inside a hot water cylinder. The water stored in this cylinder is directly available for any domestic use.
The Spanish government adopted a new Technical Building Code in 2006 which includes an obligation to cover part of the domestic hot water demand with solar thermal energy. This obligation applies to all new buildings and to those undergoing major refurbishments.
