Storage tank.
It is a 45 litre stainless steel storage tank with coil and totally
insulated using self-extinguishing polystyrene.
It has an external casing enclosed in the lower part by a flange
fixed using 12 screws.
A stainless steel double concentric coil is inserted in a pipe
(4) (coil) that passes through the entire height of the storage
tank and through the walls of which heat exchange takes place
between the hot water in the primary circuit and the water
contained in the storage tank.
This allows to keep the storage tank water at a constant tem-
perature and in the presence of a withdrawal guaranteed the
instant production of DHW.
If necessary, it is possible to extract the coil from the storage
tank after having removed the lower inspection flange.
Its regular functioning and its integrity are guaranteed by the
following devices:
Anode (1).
It is inserted into the storage tank and protects it from the
action of galvanic currents.
It is screwed onto the lower flange.
Polyphosphate dispenser (optional).
Prevents the deposit of lime scale on the walls of the coil.
This appropriate kit is mounted at the inlet of the domestic
cold water.
Pump kit (optional).
Allows to connect the pipes of any DHW pump system.
It consists in a pipe that is inserted in the boiler after the anode
and relative cap have been removed.
With the installation of the kit the anode must be screwed to
the end of the pipe.
A further kit is available (optional) including(circulator) for the
DHW circulation system.
The kit is installed within the clearance of the boiler and the
pump projects slightly below the appliances lower plastic
grid.
DHW NTC probe (B2) (9).
It allows the P.C.B. to detect the temperature of the water
contained in the storage tank.
It is fixed to the external wall of the storage tank and is inserted
inside an immersion sample point.
Safety valve unit (13).
It is a unit situated in the lower part of the storage tank in
correspondence of the domestic cold water inlet.
As well as an 8 bar valve (10) that prevents the safety pressure
in the storage tank from being exceeded, it includes:
- one filter, one 10 l/min flow limiter and a one-way valve (see
hydraulic circuit part. “5”) to prevent the consequent pressure
increase due to heating of the DHW causes return towards
the water network.
DHW expansion vessel (11) (optional).
It compensates the volume variation consequent of heating of
the water contained in the storage tank.
It is connected to the safety valve unit and has a capacity of 2
litres with factory-set pressure of 2.5 bar.
