This project was to provide and install a drain-back solar water heating system with 39 solar collectors. Solar collectors were arranged in five solar collector arrays on the roof and an exterior wall of the central plant. Work also included the installation of two 1,200 gallon storage tanks with internal heat exchangers; and, solar controllers, pumps and piping inside the central plant, and other related work. Additional work included the installation of eight additional solar collectors on an exterior wall of the central plant. These solar collectors were arranged in one solar collector array and integrated into the solar water heating system and other related work.
