Questions:
- If I see 110v to ground from black & white, why don't I see 220V across
these conductors?
- If I see the 110v to ground, does that mean that I do have power to the
heater?

Each wire should be 110 to ground, 220 if you contact both of them. The
thermostat is breaking just one wire. If it is the stat, you can get heat
by twisting the two wires together.
