sorry for the double post.

I bought and installed the rheostat for the UTH last night and now when I went to grab my snake I noticed that she was cold. I checked the connections and the level of the rheostat (which is at about 85%) and then checked the temperature inside the tank. No increase. I dig into the substrate put my finger against the glass and compared it to the area where the uth is at and NO heat at all. I unplugged the uth from the rheostat and waited to see if it would warm up. It did warm back up. So that rheostat clearly doesnt work. And I feel that I am not harming my snake by keep the uth un-monitored so I will be keeping it the way it is. The temperature is about 90-91 on the hot side and 82 on the cold.
