HEAD LOSS CURVES OF THE HYDRONIC CIRCUIT
The result of the addition of the head losses of the hydronic circuit and the available head pressure of the plant gives us the
minimum head of the circulator pump which should be installed.

HEAT PUMPS AVAILABLE HEAD PRESSURE WITH INTEGRATED PUMP
We report here the characteristic curves of the Head pressure-Water flow without consideration of head losses of the hydronic kit
(in the versions with integrated storage tank) at the maximum speed of the circulating pump.
The circuit’s plant must be designed so as to ensure the nominal water flow rate which corresponds to the operating points given
in the “TECHNICAL DATA” table and should never be lower than the values given in paragraph 18 table of "Required minimum and
recommended maximum water flow rates”.
