Holy Shit Batman! I don't mean to be rude; however I sense the need to be direct here.
Did I read this wrong or did you just say you were going to put a HIGHLY flammable & explosive liquid/vapor into an electrical device with exposed heating elements in excess of 170 degrees? I am going to bet that the switch on that unit is not certified for use in a flammable environment. What is going to happen when that liquid turns to vapor and makes its way throughout your house and you waltz back into the room and turn the switch off, or turn the room light on? (assuming it doesn't blow well before then).
Make sure your life insurance is paid up & PLEASE make sure the children are not home!
What could possible go wrong here? ☠
Step away and THINK; before you kill yourself or more likely yourself & someone else!
If you are really going to to this type of distillation, an understanding of basic science is a must. Please read, read, read. When you think you have it down; read some more.
