Reason I ask is that UTH's absolutely need a thermostat to control the heat as these can easily burn your snake (even through substrate). I didn't know about regulating UTHs when I first got into snakes and I was lucky nothing ill came of it. If it's off right now I'd look into picking up a thermostat for when cooler weather hits (or at least a lamp dimmer in the meantime) so you're prepared.
Edit: you guys type faster than me.
