water temperature in a giant rubber water tank will fluctuate less than other
tanks because the thick rubber insulates the water. The water will naturally be
cooler in the summer and warmer in the winter. With some minor adjustments
and a little foresight you can make it a low energy or freeze-proof tank.
Following are some ideas that have demonstrated success:
tank is in northern Wyoming where the temps regularly hit -20°F.
The tank was covered with 3x12's to minimize exposure to the frigid air. One
side of the tank is bermed. Two aquarium bubblers are placed in the water and
run off of a car battery. This tank remains ice free at
with no heat!
Other customers have
used "earth tubes" to transfer geothermal heat from the ground to the water.
Below is an illustration of this:
We can also leave the tire top intact and cut drinker holes around the perimeter
for livestock to drink out of. An insulated rim cover can be applied thus
maximizing the insulation quality of the rubber in the trough.
