I built ivory a new enclosure and now I'm starting on an enclosure for the Aldabra. Of course the Aldabra enclosure is going to be room size but the issue I'm already having with Ivory enclosure is heat. I have used CHE the whole time I have had my tortoises and they work but what I seeing in these larger enclosures is that the area around the CHE gets really hot and then areas further away aren't as warm as I would like. I have CHE in multiple areas through out enclosure but was thinking perhaps a different product would do a better job. So I was browsing the enclosure section yesterday and had seen a thread where someone (I think @Tom) had used these panel heaters and I got to thinking that would probably heat these larger enclosures more evenly. I was thinking of getting some but know nothing about them. Can anyone tell me how to figure out what I would need. Do I look at watt size, dimension size, etc.? Say for Ivory enclosure, it's 8'X3' from top of substrate to ceiling it's about 30" (floor to ceiling is 36") The enclosure is made of plywood, it isn't insulated but its sealed well and it's in a room that isn't air conditioned so room temp is usually around 68-78 degrees. Also can anyone suggest a place to get them/brand? Any suggestions/advice will be greatly appreciated!!
