All snakes need heat lamps and heating pads. Do not buy a heat rock they can get to hot and burn the snake. The idea is for one side to be warm and the other to be room temperature giving the snake a choice if they get to hot or get cold. Also I like the adjustable heat lamps so you don't get to hot. The adjustable ones usually have a dial on the cord that adjusts the brightness of the bulb.
