I am kind of new to this site and apologize if this has been covered. I am planning on building a batch style solar heater using 5, 55-60 gallon rain barrels. One of my first questions that could kill the project before I start is whether the pool chemistry will have problems being heated long term in these plastic barrels? They are food grade and the water will be circulating, but I just want to know if anyone thinks that I may have adverse affects due to the heated plastic. If this has already been discussed please just point me in the right direction. I am definitely looking for any tips to improve the efficiency.
Thanks in advance and I hope I can add to this forum in the future.
