My last question is; why does a rack system require a temperature controlled environment?
Heat tape doesn't do anything for air temperatures in the cage. In a rack you can use alternative heat sources like radiant heat panels/heat bulbs/ceramic heat emitters to do so.

Plastic tubs also don't hold much heat in. This means that the cool side/air temperatures in the tub are completely dependent on the temperature of the room they are in.
