What is the size of your box insideWhew, it took me a while to find you again.
My smoker is 12.5 cu. ft.
So depending on where you are located 1500 watts
probably isn't going to be enough.
One thing I have done when it is really cold out is
I made a plywood piece just the size of my smoker.
Then cut it in half, cut a hole in it for my smoke pipe.
By using this I can make my smoking chamber as
small as I need to
