Abstract
A solar collector for use in either an upfeed forced hot water heating system or a downfeed system features a pair of serpentine coils arranged in opposing flow relationship within a shallow insulated collector housing having a sealed glass closure panel. The two serpentine coils lie in spaced parallel planes within the housing, and the two coils are offset laterally so that their individual longitudinal loops overlap laterally by approximately one-half the width of each loop. The flow of heated fluid in each serpentine coil is controlled independently of the other coil by a temperature-responsive modulating valve connected in each coil close to the outlet end thereof within the housing. Efficiency of operation and practicality and economy of construction are featured.
