You heat the tubs with heat tape, just like you would with ball pythons. You can use the same rack systems too. The racks you see on Boaphile and Animal Plastics can all be used for leos too. Of course, you can always make your own rack too. But if you want to start out with just one animal as like a pet, you could go with the old aquarium and under tank heater method. Idk if I'm allowed to mention other forums here, but there are leo forums so you can google them
