I looked at Wayne's setup, and if I could be certain about the wiring, I would like that idea. I could even let the water heat while I was out milking, then just pop the can in the warm water and start stirring. I bet John could whip up a controller that would make it all work. I need to figure out a good way to mount the elements, so we wouldn't have any chance of ZAP!
If I use the band heaters, I would buy the 3000 watt one, and just wire up a double breaker, we have room in the electric box in the garage. With the water heater elements, I would need to
do that anyway.
