Finished installation - free hot water! Need to tie the units down to the rooftop, but they're in near-final position. Solar recirc pump ordered that will run during day keeping the tank at max temp (way overkill, but...cheap). Total system cost about $500 vs. 15-1800 retail installed (w/80 gal tank - way overkill).
@FireMonkey Nice! Wanna do my house next? :)
Any way to do that without the new tank? Does it work in the snow?
@TrueBloodNet
Can be done in cold weather - with different options. This is in Puerto Rico. An off grid friend has a solar tube system in SE Utah for their BnB. It uses anti-freeze system and a in-ground heat exchanger - runs his hot water and heaters with it. Also has backup propane, solar electric panels.

This is so cool!
Is there anything you could point us to to allow us to duplicate a system like this? I read all sorts of things but don’t have the correct educational or experience background to evaluate whether systems like this would work as hoped.
