Greetings Fellow Primates: I want to pipe, or wire, a solar water heating system at the farm. Considering how cheap solar panels are these days, I have been considering using electric panels and heating elements, rather than to pipe a thermosiphon (passive) or pump (active) system. First, money isn't really an issue here. I don't think the cost difference would be much, either way. In fact, I would have to build the solar collector for the water pipes to be run through, if I were to use a passive or active system. I would also have to pipe the entire hot side from the tank to the collector, and then into the existing water system. So, it does seem as though it would be a much easier route, to toss a panel or two on the roof, and wire it / them to a heating element, or two, in a tank. Then, just wire that tank into the existing water system. So, which way would you folks go, if you were starting fresh? Active / Passive water heating? Electric Panel water heating?
