My original plan was for a drain back system. I already had a below grade insulated tank. My concern is making a panel that can take the high heat. In theory, a cheaper lower temp panel can be made and kept cool with water pumping. But what happens the day the pump dies? Does the cheaper plastic tubing in the panel also die from over heating?
