Exploring the pasture
Today I built a large version of a cookie tin heater for my horse's water bucket.
I used the top 1/3 of a steel 55 gallon drum, mounted a ceramic lamp socket on a 2x4 flat and fastened it inside the drum with the bulb facing up, added a short cord and plug, installed a 200 watt bulb and set the half full 16 gallon tub on top of it. It seems to be working well right now. I wouldn't recommend it for the colder temps up north but for these cold 20 degree Carolina nights it should help keep the ice down to a minimum.
