What are you talking about if it puts off heat you can feel then it's too hot. If you touch anything that is warm you should be able to feel it and that doesn't mean it's too hot. So I'm going on the limb to say you meant other then what your post is implying.
We shouldn't have to give you a reason, it's not meant for reptiles and it's not designed in the same way a reptile one is. If you don't want to give your snakes the proper care with the right tools then in all honesty you shouldn't own a reptile.
