comprehensive list of system component materials, together with detailed accounts of solar
collector and hot water tank fabrication, and basic installation guidance. It should be read
together with Design Manual: DIY Serpentine Solar Water Heating. This second document
outlines general design principles; evaluates other designs; provides system sizing guidance,
and recommends modifications for future research.
