For the people will a enclosed belly heat rack.

Is that slight to much or no? I have read every 2 to 3 shelves I also have read one per rack. So what's correct? Are the temperature differences big enough to where you can't use the top or bottom because there to hot or cold?

The tallest I have is 8 41-qt tubs high and I've not noticed any difference. I've found there's more of a variation if the tub is warped on the bottom, which permits more of an air gap between the tub and the heat tape than the others do.
