Solar Thermal Heat Exchange Tank Liner, Exchange Coils and Pump Replacement and Solar Thermal Panels (16) and Piping Removal and Replacement of September Roof Project

The existing solar thermal system was commissioned in May 2009 on the Jail. It is comprised of 16, 4'x10' collectors with a total area of 640 ft2. producing 2345 therms annually. The system reduces natural gas fired domestic hot water heating avoiding 13.7 tons of CO2/year from being emitted into the atmosphere. Included in the system is a storage tank that has an EDPM liner and 4 copper coil heat exchangers. The system needs a replacement tank liner, replacement heat exchangers and a new recirculating pump. (Contractor to confirm tank size). Proposals Timing: 1. Panel removal/relocation: by no later than, August 31, 2022 in preparation for roof installation in September. 2. Hot water Tank liner, 4 exchange coils, recirculation pump replacement and tank cleanup. 3. Panel Reinstall and system operating by November 11, 2022, after roof is complete.
