Super Insulated Stock Tank

This is a really nice and simple design from Scott for a well insulated stock tank for horses or other livestock.

It is basically a tank within a tank with the space between filled with insulation.

This shows the two tanks Scott used.  The inner tank is a commercially available heated bucket, so with Scott's design there is no need to have a drop in the tank type heater -- the heater is built into the bucket.

Adding insulation between the two tanks -- see the full story for how best to do this.

And, this is the finished tank.

Scott uses a KillAWatt meter to measure tank heater electricity consumption, and has seen a 61% in heater energy consumption.  A drop from about 6.3 KWH per day down to 2.5 KWH per day!

All the details on building Scott's insulated stock tank...

Details on several other DIY solar and insulated stock tank projects...

Thanks very much to Scott for sending this in!



  1. If you put down a layer of tin foil inside the stock tank first and a base layer of great stuff followed by your fill and capped off with great stuff again you should be able to lift the foam plug out of the stock tank during the warmer months and reinstall the foam plug the following fall.

  2. Nice idea Rick.

    A layer of tinfoil on the blue bucket might also make it easier to take in and out for cleaning.


  3. Good idea, Rick. I didn't think of that. In my case, I don't use the stock tank in the summer when my horses are out on pasture, but I can see where the 16 gal bucket wouldn't hold enough water when the temp warms up. For 2 horses, it's fine even on the 30+ degree sunny days, with once a day filling. With 3 or 4 horses, you'd be filling it at least twice a day even in the winter.
