8.5 - Expansion tank
Provide a heat expansion control system like an expansion
tank. Make sure that the expansion tank is properly sized
considering the volume of water contained in the appliance
and in the system (see section 16, “Water contained in the
main exchanger”), also considering the working temperature
and pressure.
WARNING !!! The appliance does not have
an expansion tank. Provide the system with an
appropriately sized expansion tank for domestic
circuits as required by the national and local
installation standards. An undersized expansion tank
can cause the safety valve to trip.
The expansion tank must be installed in according to
recognised design methods. Refer to the instructions of the
expansion tank manufacturer for further installation details.
8.6 - System sizing
Size the piping and every device necessary to the system
following a recognised design method.
To size the water flow needed consider the appliance pressure
drops as reported in Figure 8-3.
