First congratulations!
I'm dying to know how you did such nicely wound coils!
I tried salt filled 3/8 copper around the outside of 1 1/2 copper but had only marginal luck with it.
Nice thing about that 2" copper is that you can run some 3/4 copper up the center of it and connect it to a solar panel if you want to expand this to a 2 heat source system.
