Thanks for the replies guys! Sorry if my question was unclear. I just had no idea what kind of heating element to use keeping safety and efficiency in mind like you guys mentioned.
I have thought about making it with the element inside the tank, so in direct contact with the wax, kind of like a water heater:
However I’m afraid that it will melt the wax directly around it and not the entire tank.
All direct heat wax melters I’ve looked at have the heating element outside the bin that the actual wax sits in.
I just got off the phone with somebody about this and he told me to take a look at something like this:
What do you guys think about that? With a barrel and one, maybe two of those elements it would be a lot cheaper than buying a new melter.
