Insulated stock water tank?

Posted by Anna264 z6 MD (My Page) on

I had an idea and was wondering if anyone had good input or advice. I'm wondering how hard it would be to insulate a stock water tank so it won't freeze in the winter. It doesn't normally get any colder than 10 degrees here in the winter. I was thinking of setting the tank on a piece of insulating styrene board, then framing the whole thing with plywood, leaving maybe a 1-2" gap between the wood and the tank, then filling the whole thing with Great Stuff expanding foam. I thought then perhaps I'd paint the plywood black to attract more sun, and probably cover part of the tank with either plexiglass or black-painted plywood so the entire surface wouldn't be exposed to the air. What do you think? Would it work? Anyone have any better ideas? The field is too far to run an electric heater.

I haven't a clue really but I wonder if you wouldn't be better off filling the space with concrete or gravel or something like that to store heat from the sun...Even milk jugs filled with water or drums of water...

Here's some info.....

RE: Insulated stock water tank?

How big of tank? What kind of animals are you watering?

I water horses in a shed, with 5-gallon buckets hanging from a wall, twice a day. They freeze, of course, and I dump out the ice.

I water sheep on the ground, also with 5 gallon buckets. They freeze, too.

If there is no snow on the ground, the sheep buckets freeze first, and have thicker ice. Obviously, the horse shed gives protection from cold.

If there is a foot or more of snow on the ground, the horse buckets freeze first, and have thicker ice. The snow insulates the sheep buckets better than the shed does.

So, I believe that an insulated container could provide a lot of protection. Based upon how well the snow works, I believe you will not have much ice developing, and the ice you do get can be scraped off the top, or dumped out easy.

Your container needs to be easily separated from your insulated box, so you can dump ice, or clean, or refill easier.

Horses are hard on anything, and might likely destroy an insulated box. That's one reason I asked what animals.

RE: Insulated stock water tank?

Thanks for all the info, especially the link to how to build a freeze-resistant tank. That's exactly the sort of thing I'm thinking of. But I guess if I did a 35-gallon barrel, I'd need to build 2 of them. Jeffrey, it will be for 2 horses to start with. I figured foam isn't that heavy, so it should still be easy enough to dump the water to clean them out.
