220v vs 110v Baseboard Heater??
Wire size isn't/wasn't an issue. I was told the 220v unit could be wired on 14/2, it's wired on 12/2 with a 20amp breaker. The portable is a 15amp unit, so when used it's on a 15amp or 20amp circuit and never tripped either. I guess I'm just curious why they make the 1000w hardwired units 220v when the 1500w portable units are 110v.
