So I ordered a 100W Ceramic heat emitter and have been using it for a while. I'm not sure if I got a dud, but it only heats to about 80-85 degrees directly below it at 12inch away, and not much at all around it. That seems low to me, since it's supposed to keep the whole tank warm at night. If my beardie isn't directly below it, it doesn't seem to heat the surrounding area at all. My beardie is 4 months old in a 30 gallon, but I'll be switching him over to a Repti-Tank soon that's 48x24x24. It gets really cold in our house during the winter, so I know this ceramic heater won't heat that size of a tank adequately, especially since it will be twice the height up at 24inches. Should I get two for each side of the tank and also should I up the wattage to maybe 200W? Has anyone else checked the temps these emit and does it sound like mine is low?
