- Hot2O Solar Water Heater DIY by FAFCO
A solar domestic hot water system by FAFCO that uses PEX tubing to transfer hot water from lightweight rooftop collectors to a storage tank upstream from your current water heater. A system controller controls the pump to ensure that water is not left in the collectors overnight or in freezing situations. Billed as the first system commercially available that can be installed by homeowners (check local codes).
