You are welcome.
BP's are not usually kept in huge enclosures. They don't use the space much. Exo-Terras are usually very nice - is it the 18W X 36L? I don't yet keep a BP, but it sounds like that would be plenty of room, depending on the snake.
Even if you change enclosures, the Herp-stat should work for the new one. The only issue for wood and melamine enclosures are that the heat pad needs to be put inside the enclosure, since those materials insulate too much.
