2. EQUIPMENT SPECIFICATIONS
The equipment supplied comprises of two principal components, the tank and the
collectors which are mounted together on a frame. The units work on the thermosyphon
principal whereby the temperature differential between the top and bottom of the system
creates water circulation thus facilitating the heating process. Two tank specifications are
available offering direct or indirect heating. Indirect heating uses a separate flow of pure
water through the collector which transfers heat to the service water through a jacket
around the storage tank. Indirect heating tanks are slightly less efficient though should be
used when the service water is highly mineralised. Tank layouts are shown below:-
Tanks are manufactured from galvanised steel plate and all have an in-built electric
booster heater and magnesium anode to prevent corrosion. They are encased in an
insulated fibreglass housing.
Collectors incorporate full area copper absorption plates ultrasonically welded to copper
circulation tubes which are enclosed in an insulated glass covered housing.
Heater systems are supplied complete with all piping connections including a bleed cock
and a pressure release valve at the tank outlet.
3. WARNING AND SYMBOLS
