Chem Geek....this one is aimed at you! i am entering the final planning stages of concurent building projects...both fairly large (in my mind...) one is a garage with a basement workshop, the other a 20 x 40 inground vinyl liner pool. i hope to heat both levels of the shop with in floor radiant heat...with the heat provided by DIY solar collectors as found on builditsolar.com. in the summer, and shoulder swimming seasons, i would like to use these same panels to heat the pool.
i know the black plastic (unglazed) solar collectors are efficient and effective and chemically inert...perfect for pool water. if i follow the BBB methods of maintaining a pool, is it possible to pump the pool water directly to copper solar collectors or would this be a total no-no due to the pool chemistry not playing nice with the copper pipe? what in specific needs to be watched or kept in check to make this work? or is this fool hearty and do i need to use a shell and tube heat exchanger (and an additional pump)?
a little off topic, but i even wonder if i could repurpose a pentair intelliflo during the winter months to pump water to the collectors in a drainback type system.
your thoughts (and prayers! are appreciated!)
