Abstract
A heat exchange element for solar heating is made of a solidified material such as concrete, cement, ceramic or resin bonded particulate material. Internal ducting is provided by embedded pipes or within the material itself. In the latter case a former is removed after the material is set, and this may be a rigid member, or one that can be dissolved or melted out. The element is preferably a laminated panel-like structure, possibly with fibre reinforcement.
