heat control options

I have a bedroom that is dedicated to reptiles. most of the enclosures are large (260 gallon, 60 gallon, 36 gallon) reptile style glass enclosures with screened tops. there are about 10 plastic Kritter Keeper enclosures that I use for smaller snakes, these have no heat source other than ambient room temps (I had lots of these around from when I had tarantulas and other arachnids) all of the enclosures with the exception of the 260 gallon have ceramic heat emitters, UTH heaters, basking lights, and UV fluorescent lights. with the onset of warmer weather it will easily get up to and over 90 degrees ambient room temp during late afternoon. I want to be able to keep the temps in the middle 80's range, would I be able to control the multiple heating devices in multiple cages with some type of Helix, Herpstat, Zoo Med brand controllers set at around the mid 80's to keep the ambient room temps down? I also thought about using an oil filled radiant heater to control the room temp and turning off the UTH and ceramic heaters. all of the lights are currently set up with a 12on/12 off photoperiod using digital timers and the UTH heaters are on 24/7. I cannot open the door for ventilation due to our Jack Russell Terrier. I do have central AC that we run on very hot days.
thanks in advance for any and all advice.

For your oil filled heater the Johnson Controls, or Rancos are your best bet. The Herpstat 2 would control 2 cages with one unit and if you need 4 probes, the Habitait control systems would be your best bet. You caould also run a small AC unit in the room using a JC or ranco.. Shoot me an email if ya like and we can get something "cooking" for ya..lol matt@mgreptiles.co
