Emergency packs and if you want to use heat tape temporarily, then i suggest going ahead and making a personalized rack. For about 30 bucks you can build whatever you want, make it fit wherever you want and heat however you want. You can make it fit your size tubs with a little measuring. A v100 thermo is about 80 bucks. Heat tape is usually around 2-3 dollars a foot. Most thermos only have one probe. Unless you have a rack, its kinda dangerous i would think to just have it out dangling by the heat tape. I have had tape fail and melt holes in parts of tubs. Luckily no noodles were hurt.
