lots of replies! I'm trying to distill alcohol without an open flame,
ethanol boils off at 78.4C (174F) and I don't want a source that is
going to constantly turn on and off because it will lower the temp and
then have to get back to where it was and cycle again and again... I
was hoping there was some sort of heating device that you just turn to
whatever temp you want and it stays there... maybe one of those $800
lab hot plates I don't know.

it doesn't seem like it would be all that hard to have an electric hot
plate that stayed at a certain temp, but then again I'm no electrician.
