Our Products

The American Solartechnics Heat Bank heat storage tank was conceived and designed by the creators of the Softank, the most popular, affordable and copied heat storage tank in the solar and wood boiler industry!

Our Heat Banks offer you the best value for your money. Unpressurized thermal storage is less expensive and with our high performance, reasonably priced heat exchangers, these tanks are efficient, simple, and affordable. They are ideal for wood boiler heat storage and are half of a solar system!

Heat Bank Highlights

* Our square tanks are more rigid and sturdy than cylindrical tanks
* Ships ready for quick assembly on one pallet
* Constructed out of high R-value Polyisocyanurate foam insulation, aluminum facing, and a steel skeleton
* Heavily insulated to minimize heat loss (only loses a maximum of 2˚F over 24 hours)
* Wall and cover panels are modular and easily transported for quick assembly
* Designed for installation in hard-to-reach, small spaces where access is limited to openings as small as 2.5' by 2.5'
* No welding or soldering in the tank for installation
* Covers come with areas of flexible foam for the heat exchangers plumbing to nest into
