I have a small, plastic 30 gallon tank that I use in the winter when it is not TOO cold. When it gets super cold I use 2 rubber very large feeding bowls for water bc you can bang the ice out of those and not break them.
You need to know your animal. Chickens won't peck at the cord on a heated dog water bowl, but horses will chew on cords like puppies do. I have to watch when I use a hose to fill the big water tank bc my QH, Buster Brown will pull out the end of the hose and play with it, thus spilling the water out and around the tank. In the winter it takes FOREVER for that to dry out.
Similarly, I had to put dummies when the two geldings have their stalls bc they both broke light bulbs. I use an outdoor extension cord and a torch light plugged in while I clean at night to see, WHICH MUST BE REMOVED else you will electrocute your horse. NO AMOUNT of training will break them of this "play."
Therefore, I don't trust ANY water tank heater with my horses. You put in SO MUCH training, that to lose a horse to electrocution is banging your head and your wallet against the wall.
