Solar Air Heating
Solar Heated Stock Tanks
What You Can Do Today
of the biggest power consumers of
winter are those electric stock tank heaters. Even though they only
keep the water at 40F, they can cost $100s per winter to operate. A
metal tank sitting on the ground surrounded by cold air does take a lot of
energy to heat, but a simple barrier of insulation and a little solar gain
has proven to solve the problem 90% of the time. Ice that does form on
the top will be much thinner, allowing the animals to break it themselves
oftentimes, and you can still use that electric heater as a backup.
Here you see the south side of the tank enclosure with the twin wall
greenhouse panel collecting solar heat. The lid is covered by EPDM
rubber roofing with an access hole cut out for access by the horses.
Here is Gary's model in action just south
