First, an aquarium is not what I would consider to be acceptable housing for a powerful constrictor like a burm. In time, it will most likely figure out a way to get out (and don't underestimate the power of a burm....rocks/weights will NOT do the trick).
Second, I am concerned about your heating approach...kind of a shot gun method. You use the word "seems" which tells me you are guessing quite a bit when it comes to temps. A heat pad should be connected to a quality thermostat so that there is no guessing. If the heat pad is inside the cage, you are asking for BIG trouble (most likely, severe thermal burns).
My recommendation would be to purchase a cage made specifically for reptiles like a Vision, Neodesha, Boaphile or Crescent Moon Creations; all are great cages and can be easily heated with heat tape, heat panels, heat pads, and even incadescent bulbs.

>>Ok well my heat pad covers 1/3 of the 55 gallon tank. It is under the tank. The substrate and the glass seperate the pad from my snake. A hide covers the whole area in which the pad covers, so basically if he wants to bask he goes into his hide. The spot is not hot too the touch and is only warm and I could not see how it could harm him, but several thermometers tell me that it is about 100 degrees in there yet he spends a lot of time there and it does not seem to hot. Is this too hot? Should I lower it some how? If so how can I do this. It really does not seem to bother him, and it has been like this for 6 weeks since I got him.
>>Thanks in advance
