So I'm almost done with my trash can build. The 1000w coil was only getting it to 180-200. So I went out today and picked up a 1500w trough warmer for horses. It was thermostatically controlled mean once the water would turn 40° it would turn on. So I dissected it and broke it down to just the coil. Now my 1000w coil was a portable burner with a control knob. Essentially all I did was unplug the old coil and plugged in the new coil. It did start getting hot but the contact points in the dimmer switch got glowing red. My question is. Should I get a more heavy duty dimmer switch? And also what exactly makes something 1500 watts opposed to 1000? Is it the size of the coil? Thanks in advance
