The New Caleffi Solar Thermal Panels


Bob Rohr and his son Max installed an impressive new solar therm panel technology on the Barn on October 21, 2011.  These panels feature a new drain-back technology patented by Hot Rod and Max and manufactured by Caleffi, an international corporation focused on hydronic technology and based in Italy.   The Rockspan barn is the second installation of these cool new panels in the United States.
