This true but have also heard wild stories about the loop not standing the test of time and contaminating the pond with glycol. Not a problem if you are using well water no glycol.

Systems most common in this area are a vertical loop. (No Glycol)

I have only found a glycol circulating medium in solar type systems.

I can understand that Joe no one back East has any land, yards not larger than a postage stamp have to go vertical.
