Ok trying to figure out my plumbing to the side arm. I will have a circulater running 24 - 7 for my panel rads. Can I hook my sidearm to this and not have a zone valve and aquastat or is there somthing I'm missing ? Dont want to spend the $200.00 if I dont need to. What would it hurt to have it circulate 24 -7 . Dont plan on letting water temps fall below 115 F on storage.
