baseboard heater - wire size

I ran 14/2 wire for a baseboard heater in my basement, 1500watts, on 240 volt circuit (I wired to a double pole 15 amp breaker), drywall guy said I should've used 12/2 wire, since the heater is about 75 feet from the panel.

My calculation would show that each wire in the 14/2 is carrying about 6.25 amps, which I figured should be ok to use only 14/2.

Is my drywall guy right? Neither of us are electricians (obviously)!

If my calc is correct, than this wire has a 2.94% volt drop at this distance with 6.25 load. Your allowed 3%, but its better to have 0%. A 14 conductor 15amp single curcuit is not allowed to exceed 50% of 15 amps(7.25)amps. Your at 6.25 "your ok" both ways.

Thanks. You have eased my concerns, and confirmed what I heard from 2 others. The drywall guy should stick to sheet rock I think and stop scaring novice DIY'rs!
