The F10sc has worked for some people at early stages. Make sure its the F10SC ONLY. The other F10's can Kill your snake.
I now see you said open mouth breathing. Thats not good. I wouldn't say Humidity did it, Id say incorrect temps. Ive had Pythons for 30 years and 1/2 of that was normal 30% house Humidity back in the 90's-early 2000's. What I did have were bad sheds all the time. Now that we have learned so much our snakes are a lot healthier. Id get a UTH on a Jumpstart Thermostat if i was you. You asked about Regulated UTH's. Never heard of one, you need to hook them up to one. ZooMed UTH mats are fine. Dont stick them to the tank. Read the Sticky I mentioned under Husbandry Sub Forum. It shows how to use Metal Tape so if you want to move the UTH or switch tanks you can without ruining it by trying to unstick it.
This is all in the Thread Sticky. Check it out. Its great.
