Thats just a regular 110 volt hotplate/burner. I use a cast iron skillet for a chip pan.
I dont use a thermometer, but I probably should. I do alot of opening/checking/rotating racks. I know I lose lose of heat because of that, but the product comes out really good.
If I tell you any more and the guy that showed me how to smoke fish reads this I will be in big trouble!
