Operation principles
The
EGO
PRIME
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 transpa-
rent 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 pas-
ses 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 conformation of the tanks means that the incoming
COLD
water does not mix with
the
HOT
output water, in this way reducing the mixing effects typical of natural and conven-
tional circulation systems.
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.
