Abstract
Disclosed herein is a tube type solar heating device in which room air is circulated through tubes located exteriorly of the building and confined in an enclosure having a reflector. The temperature of the air discharged from the outlet of the tubes is controlled by an adjustable bimetal coil which is supported on the upper door in the outlet and connected to the lower door in the inlet by a cable. The control of air flow through the tubes provides uniform temperature of the air discharged. Fans located in the tubes and connected to a separate thermostatic control are energized when the air in the solar collector reaches a preselected temperature. The fans are provided with quick change mounts which facilitate installation.
