Thanks for the video. This system is far superior than anything that is sold as "RV approved". I am a 40yr commercial electrician with just a couple of observations: 1) self regulated heat trace cable does not have a thermostat, the cable is constructed using a semi-conductor matrix around the heating cables. The cable starts conducting at about the low 40"s to high 30deg and continues to increase until 32deg when it is at full operating temp (self-regulating) 2) wrapping the cable over itself is not a problem. The cable will adjust the temp according to is rating. 3) tape the cable to the hose parallel to the length without circling the hose. This will decrease the diameter of the assembly so that your insulation will fit better and allow for easier reuse of the cable when replacing the hose. I personally use Flexillia brand hose. It is flexible and does not impart any "hose" taste. I have had multiple CAMCO leaks and bursts. 4) Finally, I use Scotch brand 88 electrical tape in a spiral installation around the insulation. This tape will remain flexible down to 20deg below and will not degrade as fast in the sun.
Thumbs up for the product options. I didn't know about the duct tape.
