Solar heating systems

Claim 1

A solar heating system for converting solar radiation into heat, comprising an elongated horizontally disposed level heat absorbtive element extending east and west having a horizontally level underside at right angle to the force of gravity, said underside being adapted for good solar radiation absorbitvity, a horizontally level transparent pane underneath said heat absorbtive element, a space between said underside and said pane to contain a level layer of dead air, an insulating housing to cover said heat absorbtive element and having side walls supporting said transparent pane and confining said layer of dead air, reflector means having a reflective surface below said heat absorbtive element and said pane arranged at such angle as to receive solar radiation and to reflect it through said pane to said underside of said heat absorbtive element to convert said radiation into heat, said reflector means (are) being movable and adjustable by adjusting means to focus the solar radiation reflected by said reflector means onto said horizontally disposed heat absortive element when in the operative position, (and) means to controllably render said reflector means ineffective by tilting said reflector means towards said housing so that said reflecture surface and said heat absorbtive element are not exposed to the sun and are shielded from adverse weather by said housing, and means to conduct the heat absorbed by said element away to be used.
