I'm looking for thermosiphon system which eliminate the electric pump but you need a structurally sound roof. My especially like the Blazing Tube system but no vendor on island-

Other thermosiphon systems are Solahart which I first saw on house roofs 50 years ago looking like a flying saucer. And a competitor model sold by Interisland Solar. Both of these located in the Kaloko Industrial in Kona anchored by HD. I think Interisland supplies a lot of the components like Gexpro in Hilo but i think gexpro handle more electrical parts.
