A rheostat is better than an unregulated UTH. I have used rheostats from Home Depot for a long time on everything from UTH to heat lamps and ceramic heat emitters. They are better than nothing and if your UTH does short out or go crazy, it is limiting the voltage to it to begin with so it wont burn your snake. The downside though is there is no safety shutoff on lamp dimmers and assuming you are keeping your snake in a room that is either warmed with something like a room heater like a reptile room or you keep your house fairly warm, you shouldn't have to adjust too much. I keep my house set to 70f and I almost never need to adjust my dimmers. I also check on my snakes and lizard a lot as they are all pretty social and really like the interaction. But yes a thermostat is still the best, even something like a Hydrofarm which is only $35.
Lol honesty im no sure why I keep responding to this gals threads as she doesn't listen to anyone anyways. Guess I must really be that bored![]()
