Why does the temperature gauge act erratic goes from cold to hot quickly then drops to cool on a 1993 mercury villager?

Can be a defective temperature sending unit. If you just chance the coolant can be air trapped in the cooling system. You would need to bleed all air from the system. Can also be a defective gauge, but highly unlikely.

The only power used by a gas water heater is the small current generated by the thermocouple that keeps the gas valve open. It comes on mechanically when the water temperature drops. You don't need house current.
