Plumbing Free Solar Thermal Panels Outside

Making more progress on our free heating system for the garage. I removed these solar panels off someone's roof for FREE! This winter they should heat the garage (maybe). In this video we are making more progress soldering the connections. Also a little peak into how I will be controlling the system (Arduino).

Thanks to Wim for the help with the Arduino
Thanks to Grandma and Grandpa for the few hours of babysitting which let me get more work done.
