The unique collapsible tanks make it possible to provide easy installation of adequate storage for most applications because the tank is light weight and only 19 inches wide in the crate. 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. COLLAPSIBLE WATER TANKS Tanks to 1205 gallons are 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 FreeHotWater 2146 Bering Drive, San Jose CA 95131 Tel: 408.432.9900 Fax 408.872.4142 Web http://www.freehotwater.com 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 wood burning 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
