We've got water buckets with built-in heaters in the bottom...and a
heater in the bottom of the big rubbermaid-type tank as well. 
Each side of the barn has its own GFI circuit but that each of two GFI
circuits can account for at least 2 buckets each on it.  I've
noticed that the horses don't appear to be drinking as much as I would
like them too...the water is not too warm and in fact feels slightly
cool to the touch.  
Is there any way to test if there is a weak trickle charge getting into
the water that may be preventing the horses from drinking as much as I
think they should be?  I'm not noticing anything when I put my
hand into the bucket.

Thanks,
Val
