iv been looking for inside mounting reptile heaters for a while and wow...EXPENSIVE..but check this out at wally world i found a small space heater with a digital thermostate that will keep a 80 degree temp. this thing is awsome for me because in my garage it gets in the 40s at night, but with this wall mounting heater inside my enclosure i put the thermostate at 75 degrees and it keeps the whole enclosure within a few degrees..awsome product and tons of saftey features on it. if you have a large enclosure and are looking for a wall mounting digital thermostate space heater this is it for only 22 bucks it will heat from 60-80 degrees.
