Well I wired it up with 240 today. My meter actually read 246v. It seemed to run just fine I didn't run it long as we are getting a lot of ice today and didn't feel like getting the garden hose out. I ran it for 30 seconds or so just to verify that it at least kind of work and it appears to work fine. The coil got warm to the touch within that 30 seconds so I shut it down.
All in all I'm very happy with it..
Now all I have to do is decide how I want to install the ground loops. I know a guy at work that has a friend that has a drill rig that they have used to install there own geo systems. Or I can do slinky loops as I have the yard to do it in. And I think my uncle has a backhoe
