We recently switched from boarding to renting a barn. The turnout paddocks have the big rubbermaid water tubs (130 gallon?), but no heating elements. I’m in north-central Ohio, so I need something that will keep the water from freezing, since I still turn them out almost every day, even in winter. I was thinking the ones that go through the drain hole would probably be best so they can’t mess with it.
Any specific brand recommendations or problems to watch for with the drain plug type?
Is it ok just to run an extension cord from the barn to the tank?? It’s not far, but I’m worried about having a cord exposed to all the elements. It would have to cross over part of the gravel drive, so would get driven over periodically too.
