Abstract
A solar heat collector has a breather tube to provide communication between the ambient air and air in the airspace of the collector through desiccant material. In this manner, the air pressure in the airspace is equalized to the ambient air pressure without moisture moving into the airspace and the desicant material is regenerated.
