heat tape is only truly safe when it cycles on and off and never reaches a temp high enough to melt things. The only way to accomplish this is to have a room with an ambient semi close to desired final temp.
example: desired temp of tub to be 80. Room temp 70.
initial heat cycle: heat tape runs 10 minutes straight to raise tub temp to 80 degrees. Then cycles off. Tapes turns on and off a few minutes per hour to cycle from 78 to 81 degrees trying to maintain 80 degrees.
The trick is selecting the proper sized heat tape for your tub size so it heats the tub fast enough.
i personally like running multiple strips of 3" spaced 2" apart rather than running a single piece of 11" (less wattage used)
