I don't think a heatsink is necessary but a couple times it has gotten quite warm when trying to get the last of my oil out of a 1701
Yes, mine too. It got a bit too hot to touch and I when that happens the vapor is quite hot and dry as well. The heat sink is a good idea, or maybe a small bubbler? Never used either myself. Anyone got any thoughts on this?
What is the best heat sink and bubbler for this unit?
