Welcome to American Solartechnics

American Solartechnics specializes in the most advanced and modern heat storage options for renewable energy heating systems today, the Heat Bank! The highly insulated Heat Bank storage system is one of the most affordable and versatile products on the market. We offer many different sized Heat Bank storage tanks along with heat exchangers to fit every system's needs. Need a custom size storage tank? We can do that as well!


We also offer custom liners for "built on site" tanks or to replace an old tank liner. Our lining system is a high temperature thermoelastomer, which is custom run exclusively for American Solartechnics!


All of our Heat Banks are easily assembled, in an hour or less. The largest component of our largest tank is 30" wide by 88" long by 5" deep and weighs about 15 pounds. The versatile modular nature of the Heat Bank makes installation of large amounts of storage in tight or otherwise inaccessible space to other storage tanks a simple task for one person using a Heat Bank!

Lifetime Heat Bank Liner Warranty

Here at American Solartechnics, we take pride in our workmanship and stand behind our products 100%, which is why we are upgrading the liner warranty on our patented Heat Banks.  American Solartechnics warrantees all Heat Bank liners for life.


This is a non-transferable warranty for the lifetime of the original Heat Bank installation. This warranty covers materials and liner workmanship only. This warranty covers all Heat Bank liners fabricated by American Solartechnics, used in conjunction with American Solartechnics heat exchangers, or in installations without heat exchangers (i.e. drain back installations). Using third party or homemade heat exchangers in a Heat Bank liner voids the warranty. Overheating damage is not covered. Our liners are rated at 180˚F continuous and 200˚F intermittent. Warranty card must be filled out and submitted to AST once the liner is in service for full coverage. Liner must be installed as per directions in the Heat Bank assembly manual.
