ABSTRACT:
The disclosed passive solar heater system defines a three dimensional tube array for conveying liquid between an inlet and an outlet, including a serial flow path through a heating stage, and possibly also a preheating stage. The heating stage has adjacent substantially straight parallel runs, with alternate ends interconnected to define a cage-like serpentine pattern. The straight heating stage runs of the tube array extend in vertical orientation, substantially over the full height of the tube array; and are in a generally cylindrical pattern, annularly and outwardly spaced from any preheating stage. Several embodiments of preheating stages are disclosed; and of the manner of enclosing the tube array for yeilding high thermal outputs. The tube array is enclosed in a transparent housing that may be adjustably vented.
