No just one uth on the side with his hide, then on the other side a heat lamp above his cage. I keep my house at 75 but in between the heater coming on it drops to low 70's which is why I have the heat lamp on the side that doesn't have the uth. And the uth surface temp on the substrate is 90 degrees. He stays in his hide most of the time this is the first time I have seen him do this, also he just finished a shed two days ago.
