domestic hot water head losses
Each boiler offers certain resistance on the passage of
the domestic hot water (see flow rate/pressure graphics in
figure 4.9). The installer or design technician must take this
into consideration in order to guarantee the correct flow rate
of domestic hot water to the utility.
