How does it heat? What is the heat tape/cord configuration? Multiple connections, or just the one at the plug?
Also, it would be a good idea to give AP a ring. They've always been very helpful with any rack questions we have.
In the meantime, throw a room heater in your snake room and bring the temp up a little if you are concerned about them being too cold.
