Really complicated. Housing three different species with entirely different temp ranges make the choice difficult. Not knowing the style of rack open or closed makes it complicated. Not knowing the ambient temp of the room in which the rack is placed really complicated.



Knowing these answers priceless....



Dave gave the basics but I will add a few more.



Belly Heat tends to work better in open rack designs.



Back heat finds its niche in a closed rack.



It is possible to control each tub in a rack with a dimmer individually but it gets a bit complicated and expensive wiring 10 dimmers.



It is also possible to wire each individually and wire the rack together as a whole by having two circuits each with their own series of heat tape. The first could be a given series of tape designed to maintain the ambient temp of the lowest heat requirement. IE maintain the temp of the entire rack to 75°F. The other series of heat tape could be wired individually to supplement the main heat and adjust the heat for each tub to the appropriate level.



Either way animals requiring the warmer environment should be placed higher in the rack to take advantage of the notion that warm air rises. It is the most economical..
