I also plan to have the heating cable inside an aluminum enclosure, thermostatically controlled to avoid tank contents from freezing. I hope I can either limit the current into the cable or operate it on a very low duty cycle. I may renege on using this 120V cable in favor of a 12V cable if I can get a good deal on the 12V.
We have used aquarium heaters in waterers for chickens. Downside is they try to heat to 80F or something, which they would never reach. About same as having a light bulb on- it stays on full-time.
Just another idea...
