done this before on a column. the coil was housed in a section of 3" copper pipe.
once heads were extracted in the usual way, I cut the power, removed the coil, capped the top and powered it back up.
basically I removed the heads with a column and ran the hearts out in potstill mode.
mind you I was making corn whiskey, not brandy.
Give strong drink to him who is perishing,
And wine to those who are bitter of heart.
Let him drink and forget his poverty,
And remember his misery no more.
