Yes, Those of you who have made a hot water heater thermostat stay at 100 degrees. You must be of a far superior race than I. I don't know how you've done it and you should apply your skills at finding the answers to the universe as your skills may be wasted on chickens! I have tried fans aimed in every direction, water bowls, rocks, moving the stat away from the light, closer to the light, metal side down, metal side up, drilling holes in the stat casing to allow more air, 3 kinds of light bulb and trying to send it to a 3rd dimension. I still have 6 degree temp swings. I am buying that repto-stat thing when I get paid as I am out of ideas!
