Versatile Range

The Large Volume Solar Tanks are available in tank sizes up to 1,000 gallons. Heat transfer ratings reach up to 74,666 btu/hr/coil (based on 100° incoming water temperature from solar panels). Multiple coils are available per tank – coil sizes are 7” in diameter and 21” in diameter. For current list of models, please view our brochure.

Advanced Assurance

The Large Volume Solar Tanks come with a limited five year warranty. A limited ten year warranty option on steel tank with double glass lining is available. Double glass lining is not an inventory item, but built upon request.
