Abstract
A mat-shaped solar heater having multiple parallel flow channels for a heat-carrying medium. Any two adjacent ones of the flow channels have a common linear divider and at least some of the dividers terminate short of an edge of the heater. Inlet and outlet conduits communicate with the interior of the heater for allowing the medium to be introduced into and to flow out of the flow channels. Discharge conduits are provided which communicate with the interior of the heater in the region of the edge in question. When the discharge conduits are closed, the inlet and outlet conduits form the sole communication between the interior and exterior of the heater, whereas when the discharge conduits are open, the medium may flow through these discharge conduits, thereby facilitating the removal of heat-carrying medium from the interior of the heater.
