Since this garage intsallation is kind of an experiment, I am trying to use as much of the parts that came with the unit as I can. It did come with an expansion tank that I was ging to use. But, I guess that this tank is sized the the preveious owners system and may not be right for my system. More studying.
I have found a good company to buy the PEX and the heat exchangers from. The problem is that 120 feet of insulated PEX comes on a pallet. I would think this means it only comes by truck, which means if I order it from Wisconson it won't be here for 10 days or so. Do you know of a local supplier to get insulated PEX?
