No, to get the top of the substrate up to the proper temperatures, you would have to run the UTH so hot that if your snake decided to dig down, he/she would burn him/herself. You also need to consider your ambient temperatures, because UTH's do not really effect air temperatures so if the room gets below 75 degrees you might need a heat lamp as well to maintain your ambient tempertures.

You could use a UTH with just the reptile carpet, or 1/4 inch , maybe a 1/2 inch of aspen
