Heating water storage for integrated systems
Introduction
The boiler has been designed to integrate more energy sources present
in the heating system, for example: heat pump, thermal solar panels, gas
boiler, etc..., made of :
• A heating water tank made of internally painted S235JR and provided
with rigid thermal insulation, covered by a grey coloured PVC mantel: 70
mm thick injected polyurethane with thermal conductivity coefficient of
0.025 W/mK and Fire reaction class B3 DIN 4102;
• Lower fixed serpentine for the solar panels connection;
• Finned copper serpentine for the fast production of DHW, integrated,
with the appropriate fixing flange, on the higher part of the tank.
• In compliance with directive 2014/68/EU, art. 4.3.
Installation prescriptions
The hydraulic installation and the heating water storage connection, must be carried out in respect of the current standards and regulations in the place of
installation and in respect of the designer of the thermal installation prescriptions, in particular:
• The storage installation operations, must be carried out by technically qualified personnel.
• The unit must be installed in an environment void of frost and atmospheric agents.
• The unit must be positioned respecting the minimal technical spaces, keeping in mind the accessibility to the electric and water connections.
• The installation of shut-off valves that isolate the unit from the rest of the plant, as well as the discharge cocks installation/storage is necessary.
• It is compulsory to assemble a metal mesh filter on the input piping (a squared mesh with side not greater than 0.8 mm) having adequate load losses and dimensions.
• A correct positioning of the unit includes its levelling and a support plane able to hold the weight.
• Ensure that the water’s supply pressure does not exceed the storage rating value, provide a pressure reducer.
• Install the safety valve calibrated according to that stated on the storage tag.
• Install the relative expansion vessels, sized according to the capacity and use of the respective circuits.
• To avoid storage corrosion or damage phenomena, ensure that the water and the connections are compatible with the storage. The potability chemical and
physical features of the DCW must be such not to corrode or scale the copper exchanger and have a hardness of less than 15 f°, otherwise, the installation
of an appropriate chemical treatment (i.e. softener) will need to be foreseen.
• Two dielectric joints are partially screwed onto the serpentine connections. In order to ensure a proper sealing connection, it is therefore necessary to
place a suitable sealing material between the joint and the thread of the coupling and then screw the joint back onto the coupling. If any, the connecting
pipes are not in metallic meters (eg multilayer pipes) the use of dielectric joints is not necessary.
