A combined chamber and conduit device to be mounted on a roof at an elevation higher than an assembly of one or more solar radiation receptors comprises a container having a depending well portion to extend through an opening in the roof or like support structure, which container forms part of a liquid flow circuit extending from the receptors and to a heat exchange zone beneath the roof for transferring heat from the solar heated liquid, serves for filling the receptors and the flow circuit with liquid which it holds under low hydrostatic pressure while letting the liquid expand and contract with temperature changes, and has lengths of tubing extending through the well portion and the container side wall for return flow of liquid to the receptors and for displacements of gaseous fluid between a cover space over the receptors and fluid dessicating and expansion chambers beneath the roof.
