solar hot water minus the pump
I forget the term but I'm asking about hooking up solar hot water panels with the panels below the elevation of the storage tank. In other words like hot air the heated water will rise naturally into the holding tank and pushing cold water down and through the solar panels.
Can any one tell me how well this system works?
I know I could hook up a small direct solar powered pump (no batteries) to the system but I believe in the KISS ideal and the less moving parts the better.
