If you only have one BP I would recommend using a second heat pad on the cool side (with an additional t-stat) to maintain proper temps on the cool side if they are not within appropriate range.

Now if you have a larger collection having the room heated with an oil filled heater would be the best option.

Are you guys keeping your rooms at 80 degrees?
My snake room is heated at 76 degrees while the rest of the house is at 68 degrees.
