I have a full-sized iguana enclosure that needs to be heated more effectively. I've been researching my options and I think that using an infrared heat panel is the best way to go, but I'm not sure what size to get for my enclosure. Reptile enthusiasts needed!
The enclosure in question is 5' wide, 4' deep, and 6' tall, and contains several vertical and horizontal spaces for basking and climbing. The enclosure is fronted by a sliding glass shower door, is made of oak veneer plywood, and was built by my father and me about 2 years ago.
The problem we're having is that the room the enclosure in is colder than we'd like, and we're having trouble maintaining the correct heat gradient for our 3 year old iguana, Rethgar. Currently using a 125 watt ceramic heat emitter we can get his basking spot to the required temperature range (90-95 degrees, usually sitting at a comfortable 93), but the problem is that this device does not have a very large radius, and most other areas of the cage are cold enough that Rethgar doesn't like to go in them. This, of course, effectively confines him to the basking spot and doesn't give him very many options for thermoregulating (he can do it effectively and is healthy as far as we can tell, but he just doesn't get to move around very much).
Obviously we'd like him to be able to use the entire space, so we're looking at getting an infrared heat panel like the ones here
. I'm just wondering what size we need to get to provide the proper gradient of heat for our setup- preferably the ideal setup would heat the basking area to 93-95 while keeping most of the rest of the cage above 85. Does anybody have experience with large cage heating? I should mention that we're in Minnesota, so ambient temperature is a constant challenge.
