Storage tank.
e storage tank is a coil unit made entirely of AISI 316 L
stainless steel totally insulated with self-extinguishing poly-
styrene with a working capacity of 54 l.
It consists of an outer jacket enclosed in the bottom part by a
flange secured by 12 screws.
Inside is a cylindrical pipe made of STAINLESS steel shaped
like a concentric spiral (coil) that develops along the entire
height of the storage tank and through the walls of which the
heat exchange occurs between the hot water of the primary
circuit and the water in the storage tank.
is ensures the water in the storage tank is always at a con-
stant temperature and, in the case of a water request, results
in the instantaneous production of d.h.w. (20000 kcal/h or
27000 kcal/h).
If necessary, the coil can be removed from the storage tank
after taking off the lower inspection flange.
Proper operation and integrity are provided by the following
devices:
Anode (1).
is is fitted in the storage tank and protects it against the
effects of galvanic currents.
It is screwed onto the upper flange.
Polyphosphate metering unit
(optional).
Prevents scale deposits on the coil walls.
e kit is fitted at the cold domestic water inlet.
Gaudium Magnum (6).
(see Gaudium Magnum description and operation).
Re-circulation kit
(optional).
Permits connecting the pipes of any d.h.w. re-circulation sy-
stem.
It consists of a pipe that is fitted in the storage tank after
removing the anode and the relevant cap.
When the kit is installed, the anode must be screwed onto the
end of the pipe.
NTC storage tank sensor (NB) (9).
Enables the modulation board to measure the temperature of
the water in the storage tank.
It is fitted to the outer wall of the storage tank and is inserted
in an immersion drawing.
Maximum flow limit thermostat (3).
is is a clicson thermostat that controls the solenoid valve of
the Gaudium Magnum device.
It is fastened in contact with the outer wall of the storage
tank.
Safety valve unit (13).
is group is located in the bottom part of the storage unit
near the cold domestic water inlet.
Besides an 8-bar valve (10) which prevents safety pressure
being exceeded inside the storage tank, it comprises:
- a filter, a storage tank drain cock with rubber holder con-
nector (12) and an one way valve (see “5” d.h.w. hydraulic
circuit) to prevent the increase in pressure resulting from
d.h.w heating causing a return towards the water mains.
D.h.w. expansion vessel (11).
Offsets the changes in volume caused by the heating of the
water in the storage tank.
It is connected to the safety valve unit and has a capacity of 2
l with pre-load pressure of 3.5 bar.
