Solar heating system

Claim 1

Method for providing solar heating over the entire area of an upwardly facing roof structure and for providing a roof over the entire area of such roof structure, said roof structure having plural parallel spaced rafters sloping downwardly over its entire area, comprising installing solar heating assemblies on said rafters to bridge across the spaces between adjacent of said rafters over the entire area of said roof structure, each said solar heating assembly having means along each of its opposite sides adapted for connection to a rafter along each side thereof whereby said solar heating assemblies may be assembled on said rafters, each said solar heating assembly having fluid inlet means at its upper end and having fluid outlet means at its lower end and having flow conduit means therebetween for use in absorbing heat resulting from solar radiation, providing a circulating fluid reservoir adjacent the upper ends of said solar heating assemblies along the upper edge of said roof structure and exposing circulating fluid therein to atmospheric pressure, disposing the ends of said fluid inlet means to be immersed in the circulating fluid in said reservoir so that circulating fluid may be drawn through said fluid inlet means from said reservoir into said flow conduit means by syphoning action, providing a flow manifold connecting all of said fluid outlet means of said solar heating assemblies along the lower edge of said roof structure, connecting said flow manifold and said reservoir to heat extracting means for circulating fluid through said conduits between said flow inlet and outlet means and for utilizing heat extracted from said fluid, and providing sheathing means bridging across said spaces between said rafters and providing a roof over said solar heating assemblies over the entire area of said roof structure, said method providing solar heat collection over the entire area of said roof structure and providing a roof over the entire area of said roof structure.
