Thanks. The room remains a standard temp of about 70 to 75 degrees. I figured by going with the VE-300 it has a wattage of 700 watts and doing the math I'm going with 6 strips of 6" heat tape at 4' lengths. So I am going to be using 24' of heat tape and the 6" tape is rated at 12 watts per foot giving me a total of 288 watts. I would assume that by only using less than half of what the thermostat is rated for will help keep it running smoother for longer.
Am I correct in the way I am thinking? I just want to make sure I am doing this correctly and the best I can do for my reptiles.
