Use car radiators for solar collectors. Any advice?
I have salvaged 2 car radiators, they aren't leaky. I want to use them for active closed loop solar collectors. Any advice?
My current plan is to put them on the roof (in a hot box), then plumb them into an old water heater in the attic. My hope is they can recirculate glycol in a closed loop, convection only, but I may need to install a thermostat and pump. Anyone have experience in this?
I want to dump the heat to my 2 water heaters in the basement (they are plumbed in tandem, so I can use the 1st tank for solar boost and 2nd tank for final temperature control).
Heat exchangers: either the Butler Solar Wand, or Brazed Plate Heat Exchanger (single or parallel).

Any advice or suggestions hugely welcome.
thanks in advance,
