Thermosiphoning solar panels
More than 30 years ago I purchased a hot water solar panel for use in a thermosiphoning system for the roof of a small camp. I forgot the name of the company I bought it from but they were from Florida and the panel was made in Israel. Any information on Florida based passive solar system sellers as described would be great. Anyone know where to purchase panels for thermosiphoning systems. My system worked great with no controls or moving parts except I had to hand pump water to a rooftop supply tank I am thinking of using a thermosiphoning system at my house on Long Island, NY preheat domestic hotwater in the warmer months say April to November. Any feedback.
