OPERATION PRINCIPLES
The
“EGO”
solar collector with integrated storage is a natural circulation solar heating
system in which the accumulation tank also acts as an absorber (direct exchange).
The accumulation system is struck directly by the sun's rays, which pass through the
transparent cover and transfer their thermal energy directly to the domestic water, which
is contained in special steel cylinders.
The accumulator (the volume of which varies according to the selected size) is quickly
heated by the sun. The water supply is positioned in the lower part of the system; it heats
up as it passes from the lower cylinders to the upper ones and finally exits from the highest
cylinder and goes into the system (directly to the user, for preheating a boiler - see the
STARTING chapter).
The special configuration of the tank ensures that the inflow water (cold) cannot be mixed
with the outflow water (hot).
Water circulation is guaranteed by the network pressure (waterworks, well,...). When the
tap downstream of the system is opened, the hot water exits from the upper section and the
same amount of cold water enters the lower section of the system.
