I don't see you heating a cage that large with just one che. Your best option would be to have a hotspot created by a uth, che, rhp, etc and then keep the ambient temps good by heating the room with a heater. I use a oil heater in my snake room and then have a hotspot in each cage. It works great and requires less equipment than heating each cage with their own devices.
How are you getting your warm end temps ?
