Recycled Bulk Milk Tanks for Solar Heat Storage

Tom uses recycled bulk milk tanks from dairy farms for solar heat storage in some of his solar installations.

Bulk milk tank reborn as solar heat storage tank.

These tanks are made from stainless steel, and will provide a very long life.  The tanks already include some insulation of some of the surfaces.  The tanks are typically in the 300 to 500 gallon range, and the price of the used tanks is about $1 per gallon.

Tom has provided some details on using these tanks...
