TANKS FOR SOLAR HEATING

AND DOMESTIC HOT WATER
COLLAPSIBLE WATER TANKS and low temperature HEAT EXCHANGERS
make it possible to store large amounts of energy at lower temperatures and
deliver that heated water for domestic hot water pre-heat, radiant floors, ducted warm
air and warm water baseboard systems
HEAT EXCHANGERS
COLLAPSIBLE WATER TANKS
     Tanks to 1205 gallons are crated
19" wide and 54" high. Two people
can walk a large tank through a
doorway, into the structure and have
it piped up in an hour. The tanks are fully insulated as shown on the left.
Tank sizes from 184 to 1550 gallons
are 48" to 72" high. "Taller tanks"
to 5000 gallons are custom orders.

    Vertical spiral heat exchangers, 21" in Diameter and 43" tall are available for all your applications. A special purpose DUAL STACKED COIL for smaller, DOMESTIC HOT WATER packages is featured on the back of this page. The two STACKED COILS can handle up to 2 or 4 solar collectors, the 120 HEX, 5 collectors and the 180 HEX up to 8 collectors at peak solar input. Both the 120 and the 180 can be piped in parallel to 1" or larger pipe for long runs for solar arrays of ten to 16 collectors. The same multiple works for 3 heat exchangers piped in parallel.

    The 120 HEX is rated for 26,400 BTUs, and the 180 HEX for 39,600 BTUs at 120 Degrees tank temperature for space heating. These are workable low temperatures for solar heating. Few heat exchangers can match this level of performance at the price.

LEADERS IN SOLAR/WOOD STORAGE SINCE 1976
    STSS CO INC now has over 26 years of performance data for these tanks and heat exchangers. Bucknell University, Department of Engineering, ran a two year study of low temperature heat trans- fer using STSS tanks and heat exchangers. This study became the foundation for our performance and claims.
957 GALLON TANK CRATED
CENTRAL HEATING
SOLAR & WOOD WITH STORAGE
Heat Storage Tank
  • A packaged, fully manufactured, light weight tank, shipped crated 19� wide and 54� high. The length varies with capacity. You can walk it into your home, open the crate and have it ready to fill with water in less than an hour.
  • Water can be circulated in a closed loop through the tank heat exchanger, or tank water can be circulated open loop. Use both methods in the same tank if required.
  • Distribution can be designed with hydronic baseboard, radiant floors, radiators, or warm-air duct heat exchangers in a furnace or heat pump system where central air conditioning is installed. Combining warm-air and baseboard, for example, is another advantage with this system.
  • Multiple zones, both open and closed loops can be operated from the same woodburning boiler and tank system at the same time.
  • Conventional 24 volt, EMC controls, reliable and safe hardwired designs are available for switch-over to back up fuels to keep you warm and your home at a set temperature when you are away.
Spiral Heat Exchangers
  • Two vertical spiral coiled copper heat exchangers are available and are custom made for this variable tank temperature heating application.
  • The HEAT EXCHANGE COILS are piped singly or in pairs for space heating and heating domestic hot water.
  • Coils purge air automatically, critical during the initial system start-up.
  • Heat stratification in the tank assures that the hottest water is delivered.
  • Coils are designed to permit a unique piping arrangement. It allows one set of coils to heat the tank (boiler to tank) and heat the house (tank to house), or it allows the boiler to bypass the tank and directly heat the house.
  • A separate coil is used to deliver DOMESTIC HOT WATER.

There are 6 or 7 ways to put together one of these systems. It takes time for an installer to decide which method is best. To solve that problem, we have designed the EMC control. This control monitors the heating balance point between the heating load and the tank temperature and automatically switches over to the oil or gas backup after every available BTU has been provided by the tank. STSS supplies instructions and diagrams. Be sure to order this control with your boiler and heat storage tank.

STSS CO INC doesn't make solar collectors. We make solar collectors work better.
THE STSS HEAT STORAGE TANK
FOR SOLAR
RESIDENTIAL DOMESTIC HOT WATER

There's a myth that there is no alternative to heavy, round 80 gallon or 120 gallon steel tanks to store solar heated water for home hot water use. Up 'til now, they were the only tanks you could get into the front door of an existing home and down into the basement.

Now, STSS CO INC has something better.

Our smallest home hot water tank is 160 gallons. It comes collapsed in a crate 19 inches wide and weights only 121 pounds - compared with the heavy steel tanks that weight 192 to 336 pounds. A copper, coiled heat exchangercoiled heat exchanger comes with the 160 gallon tank. It is packaged and shipped separately, and weighs only 124 pounds.

To get an STSS 160 gallon tank with heat exchanger, you will pay just slightly more than the 80 gallon steel tanks. Shipping charges for the light weight STSS tanks will result in savings for your customers.

An important benefit of having larger storage is realized by the homeowner and the homeowner's family because they can now install as many as three solar collectors with one tank. The larger collector array is necessary for a family that requires a lot of hot water.

A larger tank gives carryover of heated water into the second or even third cloudy day.

Another myth is that too large a tank will dilute the energy from a solar collector. Our tanks are unique Our stacked vertical, spiral heat exchanger stratifies the heat at the top of the tank because the tank water is not stirred by incoming cold water. Stratification remains undisturbed.
