1.9 STORAGE TANK UNIT HYDRAULIC
CIRCUIT RESISTANCE.
In order to guarantee sufficient DHW flow rate,
it is important to consider the resistance of the
storage tank hydraulic circuit to be coupled to the
boiler. (Fig. 1-3). In order to connect the storage
tank unit to Immergas boilers properly, refer to
the boiler instruction book.
1.10 MAIN SOLAR CIRCULATION UNIT
COMPONENTS.
The pump unit allows you to connect the storage
tank to the solar manifold, making the water cir-
culate according to the request of the control unit.
