I have an 11" x 11" Ultratherm, and the tub I'm using is a 15 qt. Obviously the heating mat is more than half the size of the tub, so I'm going to place it partially under the tub and have nothing on top of the mat on the other side. Is that okay? Is it necessary that I tape it, or can I just sit the tub on top of it?
Also.. in regards to surfaces, is there anything I particularly should NOT sit the uth on?
Just don't wanna have a potential fire hazard or something.
