Is this made by the same people as Vulcan? Is it closer to the v3000 or v5000?

Yes, Calmat and Vulcan are made in Germany by the same factory.

What is the maximum allowable distance between the two coils? As shown in the picture the distance between the two coils in my set up is 33 inches. B

As long as the majority of the cable is wrapped around the pipe, it should be effective. The minimum distance is 1-inch space between the two impulse cables. There is no maximum, technically the more the impulse cable is wrapped around the pipe, the better and more effective the treatment will be. the further the impulse cables are from each other the less surface area the cables are capable of covering the pipe.

Will the 1 1/2" setting work on pipes that are 1" or should you just use the 1" setting? Silly question, I know, but it says "up to 1 1/2" - Thanks!

It wraps more than enough in either setting.

Grounded plug? The only outlet near my water inlet is for 2-prong.

The Calmat device works with a 2-prong power adapter. The outlet near your water inlet will work well. You can also attach a standard 2-prong extension cord to the power adapter if it is not long enough to reach.
