Yeah, I am a very anxious person. 2 heat elements for hot side = overkill, but also protection if one goes out, plus I like belly heat for snakes. I also have redundant thermostats on all my heating elements. I want to sleep at night!
As I stated, not saying my way or the highway, just what I do. Good to know an RHP works well for you though KevinK, and you have AP tanks.
I would note, and it's minor, RHP's heat the air way better than UTH heat alone, but also dry the air a little bit more. They are not bad at all, and do better than most heating elements out there. However, having both a UTH and RHP running probably drys the air a little less.
Good luck whatever you decide! Again, awesome snake and awesome owner for doing what's right for him/her.
