I'm looking into building a passive solar water heater to help keep the shop mildly warmer in the winter so I only have to wear one layer and not two when I'm out brewing or working on random projects. I had the thought the other day "How difficult would it be to build a passive solar water heater system into an oast?"
I was wondering if anybody else out there had the same thought or even tried it and how well it worked if they did. I'm thinking it could be easy as building and extra loop in the water heater system and run the coils in between the fan and the hops.
It might be difficult to control temperature though as the water heats up. Any thoughts?
