I use a 100 watt red bulb and a UTH to control the heat. I have to use both in tandem to get the temps where I want- the UTH alone isn't enough to get the ambient temps high enough. Both are controlled with rheostats but I'm getting sick of tweaking it constantly, so I want to get a thermostat like maybe a Herpstat...

But I don't know which I should hook up to the thermostat- the light or the UTH? (Or should I just get a Herpstat II and control both? Or can both be controlled with a regular Herpstat? Or maybe I should get a Herpstat for the light, and a cheaper on/off one for the UTH? o_O)

That and where exactly should I be measuring the temps? Under the hide on the warm side? Outside the hide? Under the substrate? (inch of aspen) On top?

Thanks for any advice...
A thermo stat will not work very well for the lamp. I don't even think it'll work at all.
What type of UTH are you using? If your not already using flexwatt then I suggest it as most pet store UTHs don't get very hot and can't work well with a thermostat because when you tell it to be 95F it can only go up to 90F etc.
Flexwatt is far more cheaper than any UTH but you'll probably have to buy foil tape for it to sit under the tank. It REQUIRES a thermostat, usually a digital one is best, but I've heard its ok to use the non-digital ones as long as your not using it for incubation.
You put the thermostat probe at the lowest place your snake could get to to get warmth. :]
So if he burrows, underneath the aspen, right above the UTH.
