Large Commercial Solar Water Tanks

Unpressurized 120-5000 Gallons sizes

STSS large scale solar storage tanks are the most cost effective means of large scale thermal storage.  With sizes starting at 120 Gallons to 5000 Gallons, our large commercial solar storage tanks have the advantage of going through any size door as they ship on a pallet just 19” wide x 53” high.  This is very important as access to boiler rooms makes installing larger commercial solar tanks difficult if not impossible.  Even more amazing is our solar storage tanks can be assembled within an hour from uncrating! 

The tanks can be fitted with any number of through ports that connect to your piping via a 1” FPT fitting.   In an open loop configuration solar water is drawn in from the bottom port and hot returning water is returned in the upper port.  This means the top layer is always the hottest.  This stratification allows the system to deliver results even when the entire tank is not fully loaded

The tanks are not designed for potable water rather buffer energy through water storage and this energy is transfer to and from the supply and loads via internal copper heat exchangers.  These heat exchangers can be sized to fit the demand and supply loads of virtually any project.  From domestic hot water to space heating as well as swimming pools, these heat exchangers can be sized to match any project.  They are 3/4" copper coils and come in lengths up to 180 feet which can be combined in parallel for even larger systems.  We can help you with sizing so give us a call 1 800-759-8990.
