I have a base heater for my 3 gal double walled galvanized waterer but I found the whole apparatus awkward in the coop. I had purchased a 1.5 gal electric dog water bowl for the barn cats, and ended up trying it in the coop. It's far better and the cats like the poultry setup. it has wire around the cord to protect from biting/pecking (Farm Innovators brand).
I keep a catch bucket in the coop porch and a plastic measuring cup to ladle the old water, then wipe it with a rag and refill from a jug- much easier! No lugging waterers in and out of the coop. When it's above freezing I continue to use it but unplugged.
