Within the next few months I want to get rid of my space heater that I have in my reptile room (a $200 electric bill does not agree with me) and replace it with something else. I have 2 4ft long, 2 ft high, 2 ft wide wooden enclosures that I made for our bearded dragons (covered in tile) plus 5 10gallon tanks, 2 20 gallon tanks, 1 29 gallon tank, and 1 40gallon tank that are on again off again since I buy reptiles from a breeder friend resell them. I'm looking for reviews on the heat ropes, radiant heat panels and the heat mats. I was thinking of using the heat ropes for the actual tanks and would prefer to stay away from the heat mats because it didn't work too well for me years and years ago. Then again, I could have been using it wrong. Reading, the heat rope more or less works like the heat mat so I wasn't too sure about it. Has anyone had better luck with on than the other? I plan on using a 80watt radiant heat panel for each of the beardies' enclosures since that'll cover almost half of the ceiling. I'm really interested in review on the panels because i can't find much of anything about them :/ If I'm missing any other heating devices that work well for heating cages please do inform me Thanks for any help.
