Welcome! Here are some tips for using this forum.
Why has the Geo industry not yet started utilizing exp tanks and air separators on closed loop systems? Every Geo contractor that I talk to has air problems with closed loop. They have even gone so far as to make a kind of open tank that is inline with the piping. This lets air out and they pump off the bottom of the tank to ensure they always have water at the pump inlet. But now they are oxygenating the water.
The Hydronic industry has addressed this problem a long time ago. One would think the Geo industry would follow suit?
